I have now repeated the crash with packages installed only from the

Can you try the attached patch, on top of the current testing package?
Drop the file in debian/patches, add it to 00list and rebuild the
package.
I believe this should fix the issue.
I'm afraid not. There's a minor build issue to do with checking for
<avcodec.h>, rather than <libavcodec/avcodec.h>:
checking avcodec.h usability... yes
checking avcodec.h presence... no
configure: WARNING: avcodec.h: accepted by the compiler, rejected by the
preprocessor!
configure: WARNING: avcodec.h: proceeding with the compiler's result
checking for avcodec.h... yes
But the main problem is still present:
Program received signal SIGSEGV, Segmentation fault.
