Comment 1 Dario Andres 2008-12-19 18:47:43 UTC

I can reproduce this here, but I think I got the "Delete folder crash".
But there's something new : "SelectionManager" (not in my backtrace)

Here using:

Qt: 4.4.3
KDE: 4.1.85 (KDE 4.1.85 (KDE 4.2 Beta2))
kdelibs svn rev. 898705 / kdebase svn rev. 898705
on ArchLinux x86_64 - Kernel 2.6.27.8

Backtrace:

Application: Dolphin (dolphin), signal SIGSEGV
0x00007fa8e2a65fd0 in __nanosleep_nocancel () from /lib/libc.so.6

Comment 2 Peter Penz 2008-12-19 19:04:23 UTC

The second trace indicates another KDirModel issue, but I'm not 100 % sure... I've set David to CC.

Comment 3 Frank Reininghaus 2008-12-19 20:18:32 UTC

The backtrace of Darío's comment 1 looks like bug 177125. I don't know if the original report is also related to that one...

Comment 4 Peter Penz 2008-12-20 14:01:19 UTC

Thanks Frank for comparing the backtraces. I've set this as duplicate of bug 177125 - David got so many KDirModel tickets during the last weeks, that it might be easier if he has collected them as part of bug 177125.

Only 4 days until Christmas and I'm bombing David with KDirModel issues - I'm feeling guilty ;-)
