As Gregor said on irc, it's a bit of a hack. Ultimately, the code would
be factored so that BIF_read_homefile() doesn't do any UI stuff and it
can be safely called from the background code.=20
Since this patch does fix a crash with the current code (and the
surrounding code isn't as clean as possible at the moment either), I'm
inclined to commit it, with the addition of a comment summing up the
above.

Ton, do you agree reading the preferences makes sense while
backgrounded? As far as I can see there are no dangerous side effects,
but someone who knows the code better should comment.
