How to deal with #307726 ?

["Carlos Z.F. Liu" <carlosliu@users.sourceforge.net>]

Hello mentors,

In Bug#307726, some users reported that the Close button in the About
dialog is noneffective. It only happened when users were using gtk 2.6.1
or 2.6.2. The problem would be fixed after they upgrade libgtk2.0-0 to
version 2.6.4. I read the source code of leafpad, and didn't think it's
leafpad's fault.

How can I deal with it? Should I reassign the bugreport to libgtk2.0-0?
In the next release of leafpad, should I specify libgtk2.0-0 (>= 2.6.4)
manually?

Thanks.
