Hi

OS: kubuntu 11.10
KDE: 4.8.1
KTorrent: 4.1.3
libktorrent3: 1.1.3

From the script page when I try to click on the config button of one of the provided script (E-Mail notifications, Automatic Remove etc.), KTorrent crash. When started from the command line this is the output:

Code: Select all

KCrash: Application 'ktorrent' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/remi/.kde/socket-rommel/kdeinit4__0
Warning: QSocketNotifier: Invalid socket 31 and type 'Read', disabling...

After further investigation and after developing a custom script, I've seen that apparently the crash is caused by the call of an external .ui form file with:

Code: Select all

widget = forms.createWidgetFromUIFile(page,KTScriptingPlugin.scriptDir("email_notifications") + "emailconfig.ui")

Infact in my script if I use only the Kross.module("forms") and create widgets from the code via .createWidget I have no problem.

Same happen with KTorrent 4.3~git20120317

Any ideas?

Post the backtrace of the crash

The backtrace via KDE crash handler:
