Floating point exception in the client

[jpschewe]

I recently upgraded to version 2.2.0-2.2 of the client using the ubuntu repository
deb http://download.opensuse.org/repositories/isv:/ownCloud:/desktop/Ubuntu_15.10/ /
I am running Ubuntu 15.10.
I noticed that my client icon was disappearing so I ran it from the command line. It started out fine and did a sync. After some time I noticed the icon was gone. I checked the terminal window and had:
{{{

owncloud
Floating point exception (core dumped)
}}}

Here is the back trace from gdb:

The end of .owncloudsync.log contains this after the last file that was synced last night:
{{{

=#=#=# Syncrun started until (0 msec)

=#=#=# Syncrun started until (0 msec)

=#=#=# Syncrun started until (0 msec)

=#=#=# Syncrun started until (0 msec)

}}}

The timestamps on the dot files in my owncloud directory show that the client last wrote to the files about 45 minutes before I woke up. This means it ran about 8 hours before crashing.

I'll run the client in gdb this time to see if I can catch something else.

Please report in the client repo: https://github.com/owncloud/client/

Also the missing icon already has a lot of open issues, so you can have a look at those, e.g. owncloud/client#4693 (comment)
