Bug#249: Segfaults in x2goclient as well as in pyhoca-gui (both stable on Wheezy) when trying to connect to a nightly server on Ubuntu 14.04
Hi,
I just installed x2goserver (4.1.0.0-0~971~ubuntu14.04.1) on Ubuntu 14.04 Trusty and connected to it with x2goclient (4.0.2.0-0x2go1+git20140410.586+wheezy.main.1) and later also with pyhoca-gui (0.4.0.9-0x2go1+git20140108.1126+wheezy.main.1).
Both segfaulted while they worked fine when connecting to Wheezy servers with x2goserver stable.

The segfaults on the Wheezy based clients vanished when I downgraded the packages on Ubuntu 14.04 from the nightly debs to the stable debs (i.e. x2goserver downgraded from 4.1.0.0-0~971~ubuntu14.04.1 to 4.0.1.15-0~847~ubuntu14.04.1)
HTH.

Hi Axel,
I don't think that this is related to #249. (see below).

Both segfaulted while they worked fine when connecting to Wheezy servers with x2goserver stable.

()The segfaults on the Wheezy based clients vanished when I downgraded the packages on Ubuntu 14.04 from the nightly debs to the stable debs (i.e. x2goserver downgraded from 4.1.0.0-0~971~ubuntu14.04.1 to 4.0.1.15-0~847~ubuntu14.04.1)
HTH.
Kind regards, Axel
Can you please try to re-install x2goserver from the nightly builds
and check if the issue is gone?
Two commits ago, code was added to x2goserver that requires a DB
update. I have now added this call (x2godbadmin --updatedb) to the
postinst script of libx2go-server-db-perl.
Regards, Mike
