Windows seafile-applet 7.0.7 crashes - access violation in Qt5Core.dll

Seafile Client
1

Windows 10 seafile client 7.0.7 was installed recently and was working for a few days. Today seafile-applet.exe began to crash. It seems to be an access violation in Qt5Core.dll.

Multiple reboots and uninstall/reboot/install/reboot cycles did not help.

seaf-daemon.exe works normally.

Windows event log has the following data

Hi, i think i have the same problem on 5 different computers running windows (Ubuntu 18+19 and MacOS works like a charm). After first installation on Win 10 the client GUI works fine. Some days later the GUI and the tray icon crashed but the sync is still running.

Switiching profiles and multple un- and reinstalls fixed the problem for several days.

My way to get the GUI back to work is:

  1. Uninstall with CCleaner Unistall option or with Windows Apps&Features > Uninstall (uninstall with .msi didn’t work for me - repairing the same)
  2. Clean Registry with CCleaner Registry
  3. Delete all program and synced folders
  4. Install Seafile again (windows programs folder)
  5. Set the ibrary folder somewhere inside your user folder

Please help with a bugfix.

Thank you in advance!

Nevertheless, ty so much for developing that great service!

Now I am having the same problem on my second Windows 10 PC.

It seems that it is not related to any Windows 10 updates. On both machines the last update happened on May 15th that is before Seafile client was installed.

I am having this issue on 3 PCs already. I have opened GitHub issue 1298.

It seems that the crash started to happen after last sync conflicts (in my case Desktop.ini in multiple libraries).

Manfred,

Have you had sync conflicts recently? I caught the sequence of actions that leads to the crashes

  • seafile applet is running
  • there are some new conflicts
  • seafile applet is still running
  • reboot
  • seafile applet is started and running
  • manual sync of one library
  • seafile applet is running
  • restart seafile applet
  • seafile applet crashes
