Bug 182958

Can you reproduce it and post more info when you are at home?
When you said "change archive type" do you mean selecting the extension from the file-dialog combobox? or writing it ?
If you can reproduce the crash at will, may you read http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports and post a complete backtrace here?
There is a related file-dialog bug reported.

Thanks :)

Yes, sorry for the lack of detail. It actually doesn't seem to happen EVERY TIME, only when I have chosen to compress a folder. And then no matter what is or what is not filled on the dialog "compress to archive" --> every time  I select the archive type from the combobox --> KRASH!

So to reproduce:
1) Right-click a folder in Dolphin
2) Select Compress -> Add to archive...
3) Try the filter combobox...

This may be related to bug 176916 (also related to filter changes on a file
dialog)

Crash for me not every time too. And not when i compress folder. I tried to compress folder in my home directory and it's ok.
My problem is:
1) I have some access points in quick launch toolbar in Dolpin. This quick access points (path to folder) is for all applications not for Dolphin only.
2) I have point "A" for path: "/tmp/test/"
3) I have point "B" for path: "/tmp/test/new_folder/"

It's compressed successfull outside point "B" also in /tmp/test/ directory.
When i try to compress file (or folder) or folder in point "B" (path started from "/tmp/test/new_folder" directory) and change type of archive Ark crashed.

Cannot reproduce this in Ark 2.15 using KDE 4.5.0

This crash report is at least 3 years old and there were no further comments or status updates since then.

Therefore we believe that this crash is already fixed in recent KDE 4 versions or the backtrace is no longer applicable to the current KDE 4 sources.

If the crash still happens with a recent KDE version (4.10.5 or 4.11), please add an updated backtrace or provide steps to reproduce. For more information, see http://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

(To prevent automatic closing of this bug in the future, please set the bug status to ASSIGNED or CONFIRMED)
