font warnings on ubuntu
Steve Borho
10.10, I get 12 of these warnings:
QFont::setPointSize: Point size <= 0 (0), must be greater than 0
There are no setPointSize() calls in our code, anyone have a guess as
to where the warnings come from?

I also get them. I spent some time last night on that point.
The only thing I can conclude: before a26ce41e8d78, no warning.

Interesting. The icon theming is definitely working, the Workbench is
using the same refresh, forward, and back icons as Firefox on Ubuntu.
I guess I can live with the warnings if it's a side-effect of using
the system icons.

Are the warnings displayed immediately or is it some buffering?
I launch thg --debugger --nofork to see the moment when the error
messages are emitted. Unfortunately, I was not able to catch them.

One interesting point:
If the Edit toolbar is hidden, there is no warning at startup.

I think it is those three icons causing the noise. You can try
replacing them one at a time with non-themed icons and see if 1/3'd of
the warnings go away.

Some more information regarding these warnings.
- The warnings are raised when the view-refresh icon is displayed.
This occurs at startup of thg if the Edit toolbar is not hidden. If
the user enables it later, the warnings are raised at that time.
Additionally, warnings could be raised when the mouse goes over the
icon.
- No warning occurs when displaying view-refresh icon in other widgets
like the status widget. In these cases, the icon is smaller than in
the Edit toolbar.
- If the Ubuntu theme is changed to Clearlooks, no more warning
occurs. That theme is not using view-refresh Humanity theme icons.
- It seems that Qt is not able to use the file
/usr/share/icons/Humanity/actions/24/view-refresh.svg without
warnings.
- After modifying the file, no more warnings. Mainly, I delete lines
185-200 at the end of file.
I'm still wondering who should be blamed. Is it Qt because it raises
warnings when displaying a svg file? Is it Ubuntu because the svg file
is somehow bad formatted?
There is already a bug report in Qt since Feb 2010:
http://bugreports.qt.nokia.com/browse/QTBUG-8199

Today I started using Qt thg 2.x on my Ubuntu VM too (running from
source) and got these warnings. Then I googled and landed here. Small
world :-)
Looks like I have to live with Clearlooks...
