Thanks for the information.
Please remove below quoted hacks (especially the infamous Logitech 
Control Center) from your system, reboot and try to reproduce the 
problem. Problem with these hacks is that they load into every 
application, alter the behaviour of core system functions, often in a 
way that's incompatible or introduces new bugs - which then leads to 
crashes in applications that would perform flawlessly otherwise.
Thanks in advance.
Best regards, 
Felix Schwarz
