Description of Problem:
qt-3.0.4-6 and qt-3.0.4-7 as shipped with rawhide break KDE.
This can be seen by two symptoms:
- konsole has a "funny" font (extra wide, doublespaced)
- Passing the mouse cursor over the small icons in the
quicklauncher panel applet "wipes out" those icons,
especially those in the bottom row.
qt-3.0.4-5 (which I fortunately kept around) works ok.
Version-Release number of selected component (if applicable):
qt-3.0.4-6 or qt-3.0.4-7
Steps to Reproduce:
1. Start konsole, and admire that strange font!
1. Pass mouse cursor over quicklauncher panel applet
2. Click on panel icons
3. Wait a while
4. You'll notice that a couple of icons in the lower row of
the quicklauncher just disappear!
Strange font in konsole (doublespaced: between each
character, there seems to be an extra space character)
Icons in quicklauncher disappear
Normal font in konsole (as it was until 3.0.4-5)
Quicklauncher icons should stay put.
This problem has now been existing for over a week,
(qt-3.0.4-6, the first to break this stuff is dated June
21st), with no sign of progress (qt-3.0.4-7 has been released
with the same bug...)
The font problem is caused by fontconfig (new X font management system) trying
to merge all possible charsets into one font, so konsole sees the width of
Chinese/Japanese characters when determining the right spacing.
The (not 100% reproducable) icon problem is also caused by the switch to Xft2,
though I haven't debugged it enough to see whether it's a problem with Xft2
itself or with the way Qt uses it (the only change between 3.0.4-5 and 3.0.4-6
was adding support for Xft2).
