[Bug 1476736] Re: Crash in cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion `!scaled_font->cache_frozen' failed.

 

Yes, it is fonts related issue, as i can see now: i found a way to reproduce it.
1. Boot from live flash drive (i use 14.04.2 LTS 32-bit version for that)
2. Install 'gimp'
3. Enable Universe repos
4. Install 'gnome-tweak-tool'
5. Install 'xfonts-terminus'
(at this point, gimp will still run)
6. Run 'gnome-tweak-tool', select Fonts, and in 2nd selector from top, select 'Terminus 14'
Wait a bit when new font will apply.
Now, starting gimp, it will crash with error shown above.
Looks like it is not related with this particular font, because other mentioned reports rarely related with this font.
It is not looks like problem with font package itself (possible bugs, etc), because other software runs with it and looks properly.
On Ubuntu 12.04.5 LTS, this bug does not exist. 
Thanks.
