Bug#510966: latest mgp package doesn't display any presentation, not even included examples

[Harald Welte <laforge@gnumonks.org>]

Package: mgp
Version: 1.13a-1
Severity: critical

After running an 'apt-get upgrade' on my debian unstable, the latest mgp
version was installed.  Unfortunately, this mgp version does nothing but show a
black screen, refuse to terminate on user request and eat all CPU and memory.

This can be easily reproduced by running mgp on one of the examples included
with it, e.g. the  /usr/share/doc/mgp/examples/sample.mgp

I've tried all options that would make sense, including -o / -O / -x vflib / -x
freetype / -l / -V / -F 0,0,0.  The behaviour is always consistent and always
reproducible.

strace()ing the binary shows repeated calls to brk(), and top indicates the
process is eating up all cpu cycles available.  The program cannot be terminated
by the usual 'q' key, since apparently kbd input is never processed and the
process never reasds from its libX11 filedescriptor again.
