Seafile-applet crashes when doing download and synchronisation

I’m working with several Arch Linux Manjaro OS’s; all with version 20 and Linux-Kernel 54 or 56. Everywhere the seafile-applet is fine except one Computer, where the applet crashes if I try to synchronize. I have no idea what the reason may be. I launched the applet inn terminal to get some reaction and got it but do not understand it. Here the output: seafile-applet
lang = German, translation = (null), = de_DE

I’ve got the same problem. Did you ever find a solution?

Not really. Some days later there was an update from manjaro. After updating I could install everything as usually. Please give me pardon for late reaction of mine!
