libmirclient7 hang on client startup
Status in Mir:

Status in “mir” package in Ubuntu:

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
