not libfonts, thats a java app unrelated to fontconfig

Comment 3 Prashant 2015-05-06 14:34:43 UTC

Thanks for the update

When I ran gitk command inside code repository, I got Segmentation fault on screen and  segfault at 37435d661 ip 00007fc5b406c80d sp 00007fff6730b968 error 4 in libfontconfig.so.1.7.0[7fc5b4051000+3a000]  in /var/log/messages.

I have installed xorg-x11-xauth xterm packages to view my repository code.

however gitk run with same configuration in centos6.* vesion.

backtrace please?

Comment 5 Prashant 2015-05-07 03:55:06 UTC

Issue has been resolved after installation yum install xorg-x11-fonts-* package.

Thanks Akira and Caolan.

Comment 6 Akira TAGOH 2015-06-10 05:45:55 UTC

This seems happens when no fonts installed. and the real cause was, tk gives an invalid pointer to fontconfig. see Bug#1229991.
Reassigning to tk.
