Description Benjamin Ariel Nava Martinez 2015-12-22 16:48:15 UTC

Description of problem:
XFCE4 crashes if the Terminus font is used as the display font.

Version-Release number of selected component (if applicable):
Paquetes instalados
Nombre : xfce4-panel
Arquitectur : i686
Epoch : 0
Versión : 4.12.0
Lanzamiento : 3.fc22
Tamaño : 3.7 M
Repo : @System
Resumen : Next generation panel for Xfce
URL : http://www.xfce.org/
Licencia : GPLv2+ and LGPLv2+
Descripción : This package includes the panel for the Xfce desktop environment.

How reproducible:
Always.

Steps to Reproduce:
1. Open the "Appearance" dialog (xfce4-appearance-settings).
2. Head to the "Font styles" tab ("Tipos de letra" in spanish).
3. Change the "Default font style" ("Tipo de letra predeterminado" in spanish.)
4. Select terminus and accept.

Actual results:
The panels crash and the desktop becomes virtually unusable.

Expected results:
The font changes correctly.

Additional info:
I managed to solve the issue by changing to another TTY (tty2) and editing (vi) the xsettings file (/.config/xfce4/xfconf/xfce-perchannel-xml/xsettings.xml). I was able to do most things like changing windows (although the window changer did not appear) and change desktops, but calling the xfce4-session-logout app makes the session crash and falls back to the login greeter (lightdm).

Apps that crash have this output on the console:

xfce4-about: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: La declaración `!scaled_font->cache_frozen' no se cumple.
Abortado (`core' generado)

xfce4-appearance-settings: cairo-scaled-font.c:459: _cairo_scaled_glyph_page_destroy: La declaración `!scaled_font->cache_frozen' no se cumple.
Abortado (`core' generado)

I can also confirm that this happens on Fedora 23 x86_64 too.

I can reproduce this reliably ... Thanks for the report. I will submit a report upstream.

Comment 4 Fedora End Of Life 2016-07-19 18:37:37 UTC

Fedora 22 changed to end-of-life (EOL) status on 2016-07-19. Fedora 22 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
