Crash when resuming sync - [fatal default]: ENSURE: "_currentSync->isSyncRunning()"

[jnweiger]

Seen with OpenCloud Beta OpenCloud Beta 3.0.0.1814 (downloaded from CI)
in opensuse leap 15.6

• connect client to server
• The client syncs down my Personal space and the Shares space.
• switch both spaces to pause sync.
• Quit the client.
• Add a Pictures folder with many JPEGs to my local Personal space folder.
• env LANG=C opencloud --logdebug --debug
• The client starts with both of my spaces in paused mode. OK.
• Resume sync on the Personal folder. The client starts to sync up.

After a few seconds the client crashes

oc-client.log.txt
OpenCloud Beta-crash.log

oc-client.log.txt was produced by running the client with an additional parameter --logfile /tmp/oc-client.log and cleaning the file with tr -d \0 due to #652

The coredump file itself could not be found anywhere in the system.

Can you check with the latest build?
I fixed two related issues yesterday.

$ env LC_ALL=C LANG=C opencloud --debug --logdebug
Detected locale "C" with character encoding "ANSI_X3.4-1968", which is not UTF-8.
Qt depends on a UTF-8 locale, and has switched to "C.UTF-8" instead.
If this causes problems, reconfigure your locale. See the locale(1) manual
for more information.

Do we have an appimage with symbols?
