emacs freezes after Auto-saving done on large text file

[themusicgod1]

Seems like if I'm editing a particularly large text file (130Mb) and I'm typing while it auto-saves, emacs enters a non-responsive state (the zenity ""emacs" is not responding - you may choose to wait a short while for it to continue or force the application to quit entirely" window. comes up). Not 100% consistently, but pretty consistently.

I've noticed this as a long-standing problem since earlier emacs version. I hadn't identified it as related to particularly large files, but now that you mention it, the problem seems to always occur when running rmail or (now) gnus. I tend to have quite large mail files.

I'm not 100% sure but after looking at the stack trace I figured I'd try to disable cursor blink mode (which had been on). I haven't had this crash since. Could be a coincidence ...but generally happened about once an hour and it hasn't happened in awhile.

seems to take longer to reproduce but was able to reproduce in blink-cursor-mode off

This freeze is often associated with a bunch of what you're typing being written backwards in the current frame. I had a whole word come out this way: "nohduorp" Maybe not every time, 1/4 of the time.

After removing ibus after this comment on another bug ( https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/1421483/comments/19 ) I'm noticing emacs seems to be more stable. Anyone else who has this, are you using ibus and does removing ibus help?

[themusicgod1 (themusicgod1)]

This only seems to come up with ibus installed. I can't reproduce it otherwise.

[themusicgod1 (themusicgod1)]

for what it's worth (only happens with ibus installed):

ibus:
  Installed: 1.5.9-1ubuntu2
  Candidate: 1.5.9-1ubuntu2

Doesn't appear this is an issue in xenial.
