How to reproduce:
1. Create a new spreadsheet
2. Enter "aaa" (or something else) to the cell A1.
3. Right click -> Format cells.
4. Click the "Font" tab.
The UI now hangs, strace says:
$ strace -p 14088
Process 14088 attached - interrupt to quit
futex(0xa9d57bd8, FUTEX_WAIT, 14098, NULL
(I've tried several times, seems to be reproducible.)
This is on Frugalware, but I'm not sure if it's distro-specific:
$ grep font distro-configs/Frugalware.conf.in
If you have an idea what code part may be relevant, I'm happy to investigate, but I don't really know where to start. :)
I can't reproduce this in my environment. This is a very basic functionality, so if this was broken we'd be flooded with tons of bug reports, I would think.
SvxCharNamePage is the class that implements the font panel. It's in cui. That should be a good starting point to debug this problem.
I'll assign this to you, Miklos.
OK, thanks for the pointer. I can't reproduce this with 188.8.131.52 on an other machine, I'll try to find out if it's really 3.3.0 vs 3.3.1, or some other system library differs that causes the hang.
FWIW, it seems to be related to cups:

#10 0xac4489ff in SvxCharEffectsPage::SvxCharEffectsPage(Window*, SfxItemSet const&) ()
I mean if cups is not running, I don't get the hang.
It turns out this wasn't a bug in LO itself, but in libcups, marking as 'invalid'. Sorry for the noise. :)
