[Bug 1411866] [NEW] Unconstrained download to a directory w/o permission crashes udm

 

Public bug reported:

One of my system-image test suites creates a destination directory that
is unwritable.  Previously, when UDM tried to download a file to this
while unconstrained, it would issue an error with "Permission denied" in
the error output.  Now however, udm appears to either crash or freeze.
It becomes unresponsive to D-Bus and the error signal is never received,
thus failing the test.

Further, since it usually freezes, this affects future tests because udm
will not exit when its D-Bus exit method is called.  Eventually it gets
signal killed and then the tests can proceed.

For now, I will have to skip these tests when s-i runs under udm.  The
same tests pass for the curl-based downloader.

% dpkg-query -W ubuntu-download-manager
