Bug 201478

If Konqueror is crashing, can you get a backtrace? Thanks

Created attachment 35656 [details]
amarok got terminated after opening a konsole in the kontexmenu. most times (if error occurs) konqueror get terminated

i am sorry, i have no debug-files installed. nevertheless i tried to reproduce the crash, after some times of using the context-action therewas a crash again. amarok got killed. so it seems, that not only konqueror could get terminated, but i cant explain why this is possible. are there special interapplication signals or is it a random event? 

problem is btw reproducible with many kde-versions on two pc's with opensuse-packages.

Mh, seems like a KIO-related bug.

- Do the following: install the "kdelibs5-debuginfo" package; reproduce the (Amarok?) crash (you will get a more complete backtrace) and paste it in a new bug report against the "amarok" product.

If Konqueror is not showing the "Crash Handler" dialog to fetch a backtrace there are other ways to get it (if you have time).

The crash between the two apps may be related if the bug is inside the "file listing" code of KIO.

Thanks

trace with debug-files; amarok and alls konqueror-threads terminated.

i installed the debug-files now an tested another 50 times to produce this problem.

Thanks for the efforts...
Pasting the backtrace inline:

another of amarok and the debug-trace

The backtraces seem related to bug 192770 / bug 190535. Thanks

Thanks to solve it.

The backtrace and the use case seem to match bug 195237 (which might be a duplicate of bug 190535, as Darío said).
