Qcad 2.2.2.0 Prof with Ubuntu 11.04: Crash when opening file

[kevingtonbeare]

I am using Qcad 2.2.2.0 Prof with newly upgraded Ubuntu 11.04. When I try to open a file, Qcad crashes and I get the Ubuntu login sequence again (window requesting user name and password.)

I did not have this problem with the same version of Qcad with Ubuntu 10.10.

Thanks in anticipation
