Subject: Segmentation fault in x2goclient

Package: x2goclient
Version: 4.0.1.0
Severity: severe

When trying to connect to a x2go server I experience a first failure 
when the session should be established and a segmentation error ending 
x2goclient when closing the session window:

Can you check this against a latest build of X2Go Client?

Either install x2goclient package from

  deb http://packages.x2go.org/debian wheezy nightly

or build it from source (debuild -uc -us after cloned from Git).

Please report back, if the latest version show the same behaviour.

Thanks,
Mike

Subject: 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

Date: Thu, 8 May 2014 20:05:11 +0200

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).

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
