Bug Description

After surfing the web in firefox for a while, I observed that ibus-daemon was occupying a surprisingly large amount of memory (smem reports its unique set size [USS] as 107 MiB). This is much higher than the usage observed shortly after login (about 1.3 MiB USS).

Not sure yet if there's anything in particular needed to trigger this.

I'm seeing ibus use over 600MB after just a couple of months of uptime:
