You're right, backporting those didn't help.

Yep, that's it. If I modify the watchdog so that it never bails out then
both the message and the print dialog work alright. Of course that's not
the proper solution ;-), but it proves that the watchdog is the culprit
here. So we just have to find a way to keep it happy, see below.

Probably not much that we can do about the print dialog. And there might be
other cases where things may go awry. Search index generation comes to mind
-- we might just have been lucky there because this is a very quick
operation on Linux, but it might give the same issue on slower computers.

This really calls for a general solution where the gui informs the engine
that it should keep the watchdog happy while it's executing a callback
which may run for a while, and then inform it again when that callback is
finished. That shouldn't be too hard to do, the engine already does this
anyway when running gui-less. I'm working on it.
