Thanks Jarod, have you confirmed the patch works as advertised?

i have backported the fix for #bz243722, it will be included in 
qt-3_3_8-5_fc7_1. I will push new qt in f7 update soon. Thanks for your

I believe that this bug has not been fixed in f7 yet (qt3)?  It looks like only
the fc6 fixes were released two months ago.
Comment 6 Ngo Than 2007-08-28 13:32:35 EDT
it's built long ago but i forgot to push it out :(
i'm now building it with the security fix and will push it out when the build 
is done. Thanks for remind.
