As of late last week, the Linux Client 2.4.2 has started throwing a SegFault on startup (when starting on the command line). Previously, I had noticed issues with automatic startup, but it had been starting manually. Previously running for years.
Seeing an error on /usr/share/applications/owncloud.desktop in the journal, … it appears to be looking for owncloud.desktop;5a0b469d - might that be related?
