Gabble unit test test-debug.py fails when telepathy-glib is compiled with --disable-debug-cache:
Traceback (most recent call last):
File "/usr/lib/telepathy-gabble-tests/twisted/gabbletest.py", line 647, in exec_test_deferred
fun(queue, bus, conns, streams)
File "/usr/lib/telepathy-gabble-tests/twisted/test-debug.py", line 31, in test
assert len(debug.GetMessages()) > 0
The Gabble test suite does not know whether debug-cache is enabled or not in tp-glib.
I don't think --disable-debug-cache should be used unless you are going to run CMs on an embedded machine with hardly enough memory to support them, so this is not particularly high-priority.
