Mandriva 2010.2 32 bit
kde 4.8.4
bluedevil 1.2.3
openobex 1.6
obexftp 0.23
obex-data-server 0.4.6

with kernel 3.1.6 no pb

with kernel 32.x and 34.x (i tested many of them)

i can :
- copy a file from smartphone
- delete in smartphone
- browse smartphone directories tree
- i can copy a little file 30 KB
but if i want to copy a 1,5 MB file
then
the dolphin contents of E: becomes empty
and
no notification or a notification but progress bar does not progress

i must restart obexftp service in kde settings according to access again to smartphone

i updated obex_data_server to 0.4.6 but no progress
i updated openobex to 1.6 but no progress
i found this error just when cpying :
kernel: [ 834.367909] obex-data-serve[8608]: segfault at 0 ip b74073e5 sp bfe02438 error 4 in libc-2.11.1.so[b7394000+14b000]

It appears that obex-data-server, the process responsible for handling the communication with the Smartphone is crashing when you attempt to upload a file to the Smartphone. Unfortunately there is little Bluedevil can do about this (although it could handle the case of it going away better - providing an error message or similar).

I would suggest browsing to your device, attaching a debugger to obex-data-server, then trying to upload a file. The debugger should catch the crash, and allow you to generate a backtrace which you can report to your distribution - who will hopefully provide a bug fix.

I will pop this issue again because I'm too found similar odd behavior in kubuntu 12.40, Linux 3.2.0-34-generic (and older in 3.2.0-x builds), kde 4.9.3 and older (as I can remember all 4.9.x have this issues) but with exceptions
1). I can't copy anything to device using Dolphin (kio_obexftp) but unlike to the first post the file size doesn't mater again I can't copy anything
2). dmesg
[97710.792010] Bluetooth: hci0 command tx timeout
3). no events stored into syslog

but further
4). Like in the first post I easily browse the device using Dolphin and may even create new folders
5). I can send files to device using bluedevil-sendfile or KDE Send Files dialog.
5). in contrast to first post obex-data-server didn't crashed
6). and I can send files to device using console obexftp tool

so the problem more likely somewhere into kio_objexftp or into bluedevil...

Unfortunately obex-data-server sometimes gets stuck instead of crashing - which is likely what is happening here.
I've talked with the developer of Bluedevil and they'd appreciate it if you can file a bug report so they can triage this issue more directly.

Please include information on the version of Bluedevil, KDE, obex-data-server and bluez in use on your system in your report.
