libqt3c102-mt miscompiled in gcc-3.4 distro?

[Michal Schmidt <xschmi00@stud.feec.vutbr.cz>]

Hello,

I'm using the gcc-3.4 port of Debian/amd64.
After a recent upgrade of libqt3c102-mt (from 3:3.3.3-7.0.0.1.amd64 to 
3:3.3.3-7.0.0.1.gcc4) the Plastik widget style stopped working.
KDE Control Center now only offers the built-in widget styles (CDE, MS 
Windows 9x, Motif, Motif Plus, Platinum, SGI).

To solve the problem I downloaded the sources for libqt3c102-mt with:
apt-src install libqt3c102-mt
and I recompiled the package with:
dpkg-buildpackage -rfakeroot
When I install the resulting compiled package, all widget styles show up 
in the Control Center and I can select Plastik.

Therefore it seems to me that the binary package in the gcc-3.4 archive 
is somehow miscompiled. My g++ version is 3.4.3-1. What g++ version was 
used to compile the original package?

Can somebody confirm that libqt3c102-mt_3:3.3.3-7.0.0.1.gcc4 from the 
gcc-3.4 archive breaks widget styles?
