It's an issue known as recent depending on what engine was used to generate the iso.
https://forum.manjaro.org/index.php?topic=14833.0 https://forum.manjaro.org/index.php?topic=15231.0
Old preparer for first one is Preparer : XORRISO-1.3.2 2013.08.07.110001, LIBISOBURN-1.3.2, LIBISOFS-1.3.2, LIBBURN-1.3.2. The newer ISO is a Hybrid and is Preparer : prepared by mkkdeosiso So is this a Dolphin issue? As the workaround is to open K3b manually and select Tools>Burn Image should work normally. And don't know if this is a KDE or Dolphin issue or something else? As have this issue when I downloaded the manjaro-kde-0.8.10-x86_64.iso. As shows up wit a text icon and identified as a text file.  But burns as an iso just fine. . |

Please provide the output of "file --mime-type" against the two types of ISO image. Sounds like the mimetype recognition is failing due to missing magic bytes.

Those were examples from the thread links. For me different with iso in downloads I tried.

if you do systemsettings -> file associations -> and search individually for octect-stream and x-iso9660-image I'm gonna guess that either they're not listed or that they don't have applications associated with them and you'd need to rectify that

to rectify - in Dolphin right click the iso -> open with -> other -> enter preferred app and also check "remember application association" -> ok

Yes and tried that now all text files open with K3b. So now I had to roll back that association. As now .txt and text files association is borked. The problem is newer iso's are seen on a lower mime-type as application/octet-stream and not as application/x-iso9660-image. And can't gobally change file type to application. And has to do with mime-types not right. From the 2nd link thread.

to fix txt associations systemsettings -> search for "plain" -> remove k3b from App preference order
if you do basically the same for octet-stream and add association K3b ? I have the mime type but no association though the file pattern given is .bin

Well I'll look into it. Was more interested if this is a known bug? If not making info available so fixes can be generated. As the fixes supplied on other threads isn't for the average desktop user. As is a bug or something not updated to handle all types of iso's. As all .iso types should be handled and follow the same association. All iso's should elicit same action.

As many systems do now, we rely on mime type information to determine which application to open the file with - rather than the file extension, which is unreliable in some cases. In this case, a bug exists in shared-mime-info, which should be reported to the freedesktop.org Bugzilla. Please provide links to the respective ISO images which are incorrectly recognised in your report.

This problem is still present as of Fedora 22 (KDE). Could someone point me to the original bug report to provide further info? Thanks

One bug report is here, but that should be fixed meanwhile (it is fixed in openSUSE at least...): https://bugs.freedesktop.org/show_bug.cgi?id=80877 |

I have this issue with Debian 8 KDE 32bit.
dban-2.3.0_i586.iso shows as normal. http://sourceforge.net/projects/dban/fi ... o/download xubuntu-14.04.3-desktop-i386 shows as text. http://mirror.us.leaseweb.net/ubuntu-cd ... p-i386.iso gparted-live-0.23.0-1-i586 shows as text. http://downloads.sourceforge.net/gparte ... 1-i586.iso |

This one shows correctly here on openSUSE, haven't tried to download the others. Have a look at the mentioned bug report and try to apply the workaround mentioned there. I.e. make this change in the file /usr/share/mime/packages/freedesktop.org.xml (might be slightly different in your distribution): http://cgit.freedesktop.org/xdg/shared- ... f7331a338b If that helps, you might want to file a bug report with your distribution that they include that "fix". |
