I cannot reproduce your problem.
Are you still able to reproduce your problem?
Probably it would be good to use the latest Fedora 22.

Thanks Fujiwara. I am unable to reproduce this problem in Fedora 22, as I have
since installed the latest updates. Mozilla Firefox and Thunderbird still crash
when switching from ibus to default, but it doesn't cause a SIGSEGV.

I also don't see any crashes of firefox.
It would be good to get the backtrace of firefox or thunderbird.
Also which ibus engine is activated when you switch ibus to none?
You could check the current engine with 'ibus engine' command.

When Firefox crashes, it's not detected by ABRT. It prompts me to send an error
report to Mozilla, but there's nothing in the detail log when I try to view the
crash details. It's still reproducible when I switch input method types, but
nothing shows up in ABRT for me or the system.
$ ibus engine
xkb:us:dvorak:eng
I use ibus because it allows me to switch back and forth between the Dvorak and
US keyboard layouts.
I've had a look at the Fedora documentation for generating backtraces
(http://docs.fedoraproject.org/en-US/Fedora/15/html/Deployment_Guide/gener...)
but didn't see a way to force Firefox to generate one when it crashes. If you
point me at the right documentation, I will give it a go!

Probably firefox does not crach but terminate.
It may be good to run strace for the pid of firefox or check any error message
on standard IO.
% firefox
% strace -p $PID
I tried xkb:us:dvorak:eng but I don't see any problems.

Below is the output from strace when Firefox aborts.
The steps to reproduce are as follows.
1. I log in to Xfce. My default input method is ibus, and the default keymap is
Dvorak.
2. I start Firefox and strace. If I also start Thunderbird, it will often crash
at the same time as Firefox.
3. I go to Applications > Settings > Input Method Selector. When the applet
opens, "ibus(recommended)" is highlighted. If I change it to "No Input
Selected" it used to crash every time. It seems to be getting more and more
difficult to reproduce this crash.
Firefox will terminate and offer to send a crash report to Mozilla's
developers. The crash report generated by this Mozilla feedback tool appears to
be empty.
File /home/me/.mozilla/firefox/Crash Reports/LastCrash is empty, as is
/home/me/.mozilla/firefox/u33wig3v.default/crashes/events/0f5a45ad-f628-53a0-12651268-3ba56f26
and
/home/me/.mozilla/firefox/u33wig3v.default/minidumps/0f5a45ad-f628-53a0-12651268-3ba56f26.extra.
