Package: libqt3c102-mt
Version: 3:3.3.3-8
Severity: important
This QT version seems to leak memory. I'm attaching a test and their output, I
don't know if this problem persists with 3.3.4, I haven't tried it. I found
this leak after http://bugs.debian.org/293087 , but in that case it leaks
much more memory. Also I'm discussing this on the PyKDE mailing list.
