The attached patch adds test cases to check for this case, along with a
simpler similar test case for a file missing the ".conf" extension
(which is tested elsewhere, but always worth checking again).
This shows that the failure is an assertion:
test:job_class.c:153: Assertion failed in job_class_new: strlen (name) >
0
The backtrace in the inotify case is:
#2 0x0000000000421e92 in job_class_new (parent=0x0, name=0x6494d0 "")
at job_class.c:153
#3 0x000000000042d029 in parse_job (parent=0x0, name=0x6494d0 "",

And likewise in the non-inotify case there is a similar backtrace:
#2 0x000000000042123a in job_class_new (parent=0x0, name=0x6466f0 "")
at job_class.c:153
