I have the latest version of the desktop client installed on Ubuntu MATE 18.04, connected to both a NC12 legacy installation (for Dropbox compatibility and Contacts, since they cannot sync on NC15) as well as NC15.
File sync works properly on Mac OS X, but the client repeatedly crashes on Ubuntu. It doesn’t give an error dialog. I tried reinstalling the client, to no avail.
Where would I find the reason of this error?
