Bug#613411: ardour-i686: segfault when starting

[Adrian Knoth]

Package: ardour-i686
Version: 1:2.8.11-4
Severity: grave
Justification: renders package unusable

Hi!

When starting ardour, it currently fails with a segfault:

raptor_sequence.c:385: (raptor_sequence_get_at) assertion failed: object
pointer of type raptor_sequence is NULL.
raptor_sequence.c:385: (raptor_sequence_get_at) assertion failed: object
pointer of type raptor_sequence is NULL.

Program received signal SIGSEGV, Segmentation fault.

#8  0x0838c2bb in main ()


Since I maintain the package, I file this bug for reference and
documentation purpose.

Note: recompiling against current librdf0 (1.0.13-1) fails, so it seems
there is a larger API change in librdf:

/usr/include/rasqal/rasqal.h:1021: error: 'raptor_log_handler' has not been declared


Let's see.
