OK, thanks. Since we're not certain what the fix was (if any) then
Incomplete is the best state. If the problem doesn't reoccur in 60 days,
the bug will expire and close automatically.

Title:
  libmirclient7 hang on client startup

Status in Mir:
  Incomplete
Status in “mir” package in Ubuntu:
  Incomplete

Bug description:
  When starting up a mir 7 client on vmware (Ubuntu 14.04) it hangs in
  the following location:

      at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185
  185	../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S: No such file or directory.
  (gdb) bt
  #0  pthread_cond_wait@@GLIBC_2.3.2 ()
      at ../nptl/sysdeps/unix/sysv/linux/x86_64/pthread_cond_wait.S:185
  #1  0x00007ffff679266c in std::condition_variable::wait(std::unique_lock<std::mutex>&) ()
     from /usr/lib/x86_64-linux-gnu/libstdc++.so.6
  #2  0x00007ffff7b92e9b in MirWaitHandle::wait_for_all() ()
     from /usr/lib/x86_64-linux-gnu/libmirclient.so.7
  #3  0x0000000000401027 in demo_client ()
  #4  0x0000000000400e97 in main ()

  (This is mir_demo_client_basic from the mir_demos package)

  The mir_demo_standalone_* applications seem to work fine, and the
  mir_demo_server_* applications seem to be running nicely with a
  visible mouse cursor.

  This also happens with XMir, which is the most annoying part.

  It appears to be a regression, since I'm sure I had this running on an
  earlier update snapshot of Ubuntu 14.04

  Thanks,
  Thomas
