Bug ID: 413720
Summary: Parley crashes when I try to start practice with a
certain file
Product: parley
Version: 19.08.1
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: parley-bugs-n...@kde.org
Reporter: kirsc...@googlemail.com
Target Milestone: ---
Created attachment 123651
--> https://bugs.kde.org/attachment.cgi?id=123651&action=edit
Corrupted Vocabulary file which can be opened in edit mode, but not in practice
mode
SUMMARY
Parley used to work fine for me until yesterday - The following steps seem to
have corrupted my vocabulary file:
1. I entered practice mode and practiced both in "known -> learning" and
"learning -> known" mode, using the attached vocabulary file.
2. I opened a downloaded vocabulary file from the file menu (File->Open Recent)
3. I practiced with the downloaded vocabulary file
4. I opened the other vocabulary file again
Now, my vocabulary file seems to be corrupted, because I cannot enter practice
mode anymore without Parley crashing immediately. I can still open the file in
editor mode, if I open the file from Dolphin.
STEPS TO REPRODUCE
1. Load the attached file into Parley
2. Start Practice Mode
--or--
1. Load the attached file from the Parley Dashboard (which opens the file in
practice mode instead of editor mode)
OBSERVED RESULT
Parley crashes with a segfault (see attached backtrace)
EXPECTED RESULT
Parley opens the file in practice mode
SOFTWARE/OS VERSIONS
Arch Linux with i3wm and qt5ct
BACKTRACE:
Application: Parley (parley), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".
