Version: 2.15 (using KDE 4.5.1) OS: Linux If I open some big archive (tar.bz2) clicking it in a file manager and close the Ark window while it still extracting the files, the window closes but the ark process persists, I can see it using "top" and it still unpacking the stuff. Sometimes Ark even crashes at quitting (yes, I know about the old-time Bug 193908, but I don't know how much these bugs are related to each other). (I've chose "Happen every time" because it always either remains working or crashes.) Reproducible: Always Steps to Reproduce: 1. Open a huge archive. 2. Close the Ark window while unpacking. Actual Results: The Ark's process is still working in background (or Ark segfaults). Expected Results: Ark's process should be terminated successfully.
I think it should crash or stay in the background forever depending on the file format. Can you recognize any pattern here, and, more importantly, what backtrace do you get when it crashes?
I've tried .tar.bz2 and it either stayed in background, or crashed ark, so it seems random to me. That was in KDE-4.5.1. Since I've installed KDE-4.5.2 (the Ark version is still 2.15), this "backgrounding" may only be reproduced by closing the window instantly after it emerged, but anyways it leads to a crash very soon (after several seconds). Here's the backtrace, it looks pretty much the same as in bug 193908 : Application: Ark (ark), signal: Segmentation fault [Current thread is 1 (Thread 0x7f5db14a4760 (LWP 24518))] Thread 2 (Thread 0x7f5da06d9710 (LWP 24519)): [KCrash Handler] #6 0x00007f5db10a7327 in Kerfuffle::ReadOnlyArchiveInterface::entry(QHash<int, QVariant> const&) () from /usr/lib/libkerfuffle.so.4 #7 0x00007f5da0ee4b0e in ??
