 |
|
Just in case somebody is struggling with this. Maybe even installed FireTitle addon to Firefox and suppress window title change to current tab title...
Symptoms
xfce4-panel-4.12.0 crashes when any window title contains Asian (or non-ISO-8859-1) characters. When running xfce4-panel in terminal the following is printed consistently with each crash and crash occurs almost instantly while window titles have those characters:
xfce4-panel: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: Assertion `!scaled_font->cache_frozen' failed.
When all window titles have ISO-8859-1 characters, then xfce4-panel works just fine.
You may or may not have x11-themes/gtk-engines-murrine installed (I didn't, but I had it installed way back).
Installing media-fonts/ttf-droid (or other fonts) doesn't help (ttf-droid might help with Chrome).
What Worked for Me
Installed a patched gtk-engines-murrine. Started xfce4-panel, worked without X restart.
