Hi Andreas,

Are you saying that you will be coming out with a patch soon that will subsume 
this one?  I don't doubt that there are more bugs to be fixed, but this patch 
most definitely fixes one of them (the one that George was running into, and 
the only one he's run into so far).  I'm fine with holding off if a more 
comprehensive fix is imminent, but on the other hand I don't want to not fix 
one bug just because the patch fails to fix all the bugs...
