Template Preview in template manager dialog now freezes app

[Alex Thurgood]

Hi,

Is anyone else here having a problem with the template preview function
causing master build git pulled yesterday morning on Linux 32bit ?

On my build, when I try to preview a template using the standard GTK
template manager dialog (activating the Preview button), the whole app
freezes. I can't even get a useful trace out of gdb (or I don't know how).

In my build from 2 days ago, this did not occur, so there is some recent
change that has caused it.

Confirmation that this is not just my build would be nice.

Alex
