Created attachment 105995 [details] backtrace (~340kB) Application: ark (17.04.1) Qt Version: 5.7.1 Frameworks Version: 5.34.0 Operating System: Linux 4.4.0-79-generic x86_64 Distribution: KDE neon User Edition 5.10 -- Information about the crash: - What I was doing when the application crashed: 1) going through folders in Dolphin to the folder where I have ~1GiB rar file 2) clicking on it with LMB to open it (to check content) 3) Ark does crash almost instantly RAR packages installed: rar unrar-free Additional info about the rar file: `rar t file.rar` works, ends with "All OK", the file contains roughly 10k files in about 1k folders, including names like "RetroMusicCollection/2017/IT.To Eslaria (3'06)". `unrar -t file.rar` works as well, listing the ~10k file names. The crash can be reproduced every time. --- Tried to submit through the crash report tool at first, but got rejected due to final message being over 64ki limit.
After removing unrar-free package, and adding unrar package, the Ark does not crash any more, and opens the list of files from the rar.
Doing one more test, I created tiny text file (echo "dd" > a), rar-ed it with regular rar, and tried to test/list it with unrar-free, it seemingly worked. Then I tried to actually extract it with unrar-free, and instead of text file an empty folder was created on disk with the "a" name. So the unrar-free (1:0.0.1+cvs20140707-1) looks to be completely useless, more like a trap. Was there working version back then? Will there be? Maybe ark should conflict with unrar-free package, if it's broken like this. Then again, the crash is still happening on Ark side. Uselessness of unrar-free is different topic.
Yes, unrar-free is unmantained and we dropped support for it a while ago. Ideally ark shouldn't crash if someone is using it, but honesty I'm not sure whethet that's worth fixing. The best fix here would be removing unrar-free from debian/ubuntu repositories.
