Thanks Steve,

I think I have tracked it down.

debian/patches/libgsm.patch was only applied to configure.in, the necessary 
changes to configure wern't in the patch.

As a result, if autoconf was called and configure was regenerated it would 
dynamically link libgsm, but if configure wasn't regenerated twinkle would 
try and both dynamically and static link libgsm, hence the race condition.
