bug#13469: 24.2; emacs has a tiny frame, when I embed it in a kmail text field via xembed (--parent-id %w)

Sorry, that got lost in different shortcuts of different mail programs…

I’ll try to keep it in.

When I disable the menu bar, the frame is a bit bigger even without
--basic-display. It still resizes to the tiny size, though.

I just found a much easier way to reproduce it:

Run emacs with --parent-id <random number>

Then click with the mouse on the minibuffer. With menubar, it gets
really tiny, without menubar it resizes to a bigger size (~4 times as
wide as the small size), but when I click the minibuffer it emacs starts
to flicker and to resize repeatedly. The flickering stops, when I call
async-shell-command but starts again once I hit C-g to leave the minibuffer.

I get something like this:

I tried to check the source, but bzr just died with a maximum recursion
depth error when I tried to get the source of emacs 24.2.1 instead of
trunk… (I’m not used to bzr, so I likely sent it quite an evil set of
commands: update from trunk to emacs-24.2.1; switch emacs-24.2.1; revert
--forget-merges ; switch emacs-24.2.1 → dead)

Online I could only find this:

http://bzr.savannah.gnu.org/lh/emacs/emacs-24/annotate/head:/src/dispnew.c#L5726

A backtrace after clicking the minibuffer (which triggers a resize)
looks like this (without menubar):
