comparison of font sizes between qt-4.5.3 (left) and qt-4.6.1 (right)

Description of problem:
After updating to qt-4.6.1-3.fc12.x86_64 from updates-testing all Qt applications have slightly bigger fonts than before. I don't know if it's expected, but it's mildly disturbing for me.

Version-Release number of selected component (if applicable):
qt-4.6.1-3.fc12.x86_64

How reproducible:
always

Steps to Reproduce:
1. Start with having qt-4.5.3-9.fc12 from F12 updates installed.
2. Run a Qt-using application (I noticed it first in jabbim, but qtconfig-qt4 shows it as well).
3. yum --enablerepo=updates-testing update qt
4. Run the same application once more.
  
Actual results:
Notice the newly run instance has bigger fonts than the old one.

Expected results:
Font appearance not changing with updates within a stable release.

Additional info:
Screenshot attached.
