Description Florian Best univentionstaff 2016-06-13 08:04:54 CEST
If the log contains non-utf8-able characters the log view crashes:

Version: 4.1-2 errata197 (Vahr)

Remark: I just wanted to see the join-logs. :(
On the server the logfile is available.


Execution of command 'join/logview' has failed:
