Using eclipse.buildId=I20100706-0800

BootLoader constants: OS=win32, ARCH=x86, WS=win32, NL=fr_CA
Command-line arguments:  -os win32 -ws win32 -arch x86 -console,

I got this exception:

Unfortunately I could not reproduce. Might be a timing issue. I still report it in case I can reproduce it in the future.

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
