Hi,
seems to be happening but the result of
`g_udev_client_query_by_subsystem` is empty. This isn't even feedbackd
related code, just plain gudev + udevmock so I wonder what could be
different on alpha / hppa?

Tried to reproduce on panama.debian.net but can't get a sid schroot with
build-deps there:

$ dd-schroot-cmd -c sid_hppa-dchroot-8ecf7517-dd36-44d5-a4a2-a97d01dcb458 apt-get update
/usr/local/bin/dd-schroot-cmd:59: SyntaxWarning: invalid escape sequence '\.'
  if re.search('^\.|~$|[^0-9a-zA-Z_.~-]', session):
  File "/usr/local/bin/dd-schroot-cmd", line 124
    except OSError, e:

In case someone wants to investigate: This runs the single failing test:

  umockdev-run --  _build/tests/test-fbd-dev-led

Cheers,

Hi,

It fails in the tests that enumerate devices so likely fixing gudev will fix this here too.

Probably problem is in umockdev.  Build fails with segmentation fault in test-umockdev-vala:
do_page_fault() command='test-umockdev-v' type=15 address=0x00000010 in libumockdev.so.0.3.0[26167,f8e82000+37000]
trap #15: Data TLB miss fault, vm_start = 0x00010000, vm_end = 0x00025000
command line: /home/dave/debian/umockdev/umockdev-0.18.4/obj-hppa-linux-gnu/test-umockdev-vala

Looks like a NULL pointer issue.

I tried duplicating this manually but I haven't been able to duplicate segmentation fault.  Sixth test aborts
trying to open /dev/tty:
