Subject: reproduced and fixed on x86_64: patch included :-)
Followup-For: Bug #559142
Package: xfstt
Version: 1.7-5
*** Please type your report below this line ***
I get
xfstt[3155]: segfault at 4 ip 4085e4 sp 7fffbe604f50 error 4 in
xfstt[400000+19000]
on start-up. RandomAccessFile::RandomAccessFile(char * filename)'s
error path, on failure to open file, neglects to set absbase; this leads
to openError() failing to report that open failed, so instances think
they're OK and try to use methods that should only be used if open
succeeded - boom ! Have a trivial <patch>

Incidentally, as I initially followed your instructions: <quote src="console">

</quote> have you any idea where the core dump went ? I need to find it
to tidy it away !
I don't know what's allegedly corrupt about /usr/share/fonts/truetype/;
it looks like a perfectly sensible directory to me, with Isabella.ttf
and a bunch of subdirectories in it.
