Linux version => No GUI after upgrade. WTF?

Hey guys,

My linux machine (debian 5 stable, 32 bit) was running bitcoin 0.20 for months now.  I upgraded it to 0.36 today and the GUI won't appear, however bitcoin is running and seems to use the CPU.  Where is the GUI?  It won't appear, but there are no errors in the console when I run bitcoin from xterm.
