Description Nadav Kavalerchik 2009-01-22 14:58:25 UTC

Version:           1.2 (using 4.1.96 (KDE 4.1.96 (KDE 4.2 RC1)), Debian packages)
Compiler:          cc
OS:                Linux (x86_64) release 2.6.26-1-amd64

while rendering a movie (using kdenlive) i opened the target containing folder
and while hovering with the mouse over the movie file that was growing in size while it was rendered... dolphin crashed.

(i reopened it several time to make sure it was this issue, exactly)

after the movie was rendered completely i did not crash anymore. 

some crash report:
This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

(no debugging symbols found)

Comment 1 Peter Penz 2009-01-22 15:30:05 UTC

Thanks for the report. This looks like a strigi issue. Could you please let us know your strigi version ('strigidaemon --version')? If the issue still occurs with a recent strigi (= 0.6.3) I'd kindly ask to submit a bug report at, as strigi is maintained outside of KDE.

Comment 2 Nadav Kavalerchik 2009-01-22 16:20:18 UTC

strigidaemon --version
strigidaemon 0.6.3
 Copyright (C) 2006-2007 Jos van den Oever and others

can you direct me to the right bug report website (for strigi)

Comment 3 Nadav Kavalerchik 2009-01-22 16:22:50 UTC

btw,
logging into kde, i get this error (from dmesg)

nepomukservices[5408] general protection ip:7f8b851fa55e sp:7fff8d7e7d80 error:0 in libQtCore.so.4.4.3[7f8b85191000+230000]

do you think it is related ?

and strigi search index is disabled in System Settings and i can not enable it.
and looking for nepomuksearch:/ in dolphin return nothing.

I don't think this is the root of your issue, but I don't know for sure...

Anyway, I forgot to mention the strigi page ;-) Here it is:

Thanks for your support!

KFileMetaDataProvider: Don't crash if a Strigi analyzer crashes

Some Strigi analyzers are still unstable and crash under certain circumstances. This patch moves the reading of the meta-data into a custom process instead of doing it in a thread, which assures that a crashing Strigi analyzer does not result in crashing Dolphin or Konqueror when hovering some items.
