Bugzilla Bug 105757

wxpython (or may be wxGTK) is not yet compatible with latest pango (stable)
release 1.10.0.

When I run a wxPython based apps called, "picard". I get an ImportError.

The root cause for this should be "x font backend" is deprecated in pango 1.8.
And I think, it has be taken away fully in 1.10.

As a sidenote, pango 1.10.0 is currently package.mask'd in portage
However, as pango-1.10.0 is released with the latest Gnome 2.12
I think this issue should be addressed.

Also, if the bug report is valid, I think, this issue may be linked to gnome
2.12 bug report somehow...

Reproducible: Always
Steps to Reproduce:
1. echo ">=x11-libs/pango-1.10.0" > /etc/portage/package.unmask
2. echo "x11-libs/wxGTK ~x86" > /etc/portage/package.keywords
3. echo "dev-python/wxpython ~x86" > /etc/portage/package.keywords
4. emerge pango wxpython
5. run a wxpython based apps
Actual Results:

Hi,

This should be fixed in wxwidgets 2.6.2. Can you try that version (not in
portage yet i think)? I will try it as soon as i am back home.

Regards
Sander

wxGTK-2.6.2 works fine here without this problem when using opendict, an
application that requires wxpython-2.6. Runnig with wxGTK-2.6.1 fails due to
this pango_x_get_context error.

This bug has been fixed in the current ebuild.

It does not seem so (current unmasked ebuild wxpython 2.6.1.0):

Pending stabilization of wxpython-2.6.3.2, together with wxGTK-2.6.3.2.
However, as wxGTK-2.6.2 is free of the problem, I don't think wxpython-2.6.1
should cause problems with wxGTK-2.6.3.2 in this regard, but not 100% sure

Marking this as fixed as wxGTK and wxpython 2.6.3.3 are now marked stable on
all arches.
Please reopen if this problem persist with these versions, but I'm pretty sure
it's OK :)
