Okay. In the meantime, I've just setup a development environment for 
testing and got the following backtrace from the hung process using gdb:

(gdb) bt full

Maybe not entirely helpful, but now the test environment is set up, I'll 
have a go with a source build of 2.4.24 with full debug enabled and see 
if it is still reproducible there.


ATB,
