Description Xavier Guerrin 2008-07-28 16:14:48 EDT
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (compatible; Konqueror/3.5; fr) KHTML/3.5.9 (like Gecko)

Description of problem:
The Qt library 4.3.5 seems to be unable to render a dashed ellipse. When this 
library is asked to render an ellipse using a dashed line style, it uses 100% 
CPU and never finishes the rendering. Using a solid line style to draw the 
ellipse is enough to avoid this bug.
This bug was reproduced every time with the qt-4.3.5-2.fc9.i386 package and 
the i386 architecture. However, it never happened with x86_64 or Qt 4.4.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.See attached URL for instructions - it explains how to compile a minimal 
demo program that triggers this bug.

Actual Results:
The program took 100 % CPU and did not display the dashed ellipse pixmap.

Expected Results:
The program should have immediately displayed the dashed ellipse pixmap.

Additional info:
This bug was found while trying to run the program `QElectroTech' - see

Qt 4.4 is already in updates-testing.
