[AG-DEV] Segmerntation fault with SharedPresentation

Possibly adding a time.sleep(1) call before the 
com.sun.star.bridge.UnoUrlResolver line in 
/etc/AccessGrid/SharedApplications/Shared_Presentation/ImpressViewer.py 
might solve the problem. As I'm not able to reproduce the bug, I can't 
confirm.

I don't know if that would help.

Fedora doesn't use the OpenOffice.org version, but the one from 
http://ooo.ximian.com/ which is what most linux distrbutions that ship 
OpenOffice use, it consists of a heap of patches that get applied to the 
official OpenOffice.org version, then the Fedora version applies more 
patches on top of those. I thought one of the patches included the mutex 
patch, but looks like I was mistaken.

The only other alternative I could think of is to download the OpenOffice 
SRPM and manually applying the GlobalMutex fix to the PyUNO source code, 
unfortunatelly building OpenOffice is a bitch as it has a weird build 
infrastucture.

Cheers,
Doug
