Re: [Denemo-devel] Denemo Debian build

[Richard Shann]

You found the correct thing Ctrl-C - the program isn't crashed, it is
just hanging in an infinite loop. This seems to be a bug in the gdk -
x11 system as the
#9  0x00007ffff53ed889 in gdk_display_get_event ()
tells us that your attempt to resize was noticed and then later
xcb_wait_for_reply ()
indicates something is just going to wait, and indeed it ends up in a
poll()

It would be good if this could be raised as a bug (against what quite is
not clear of course) but it is almost certainly not a Denemo bug...

On the bright side, it *does* look like the threading bugs are gone, and
they are the worst, hitting randomly...
