Thank you for your bug report, the fedora bug suggests it's fixed in the current ibus version and I can confirm here on raring that the strace command shows no constant polling
** Bug watch added: Red Hat Bugzilla #572611 https://bugzilla.redhat.com/show_bug.cgi?id=572611 ** Also affects: ibus (Fedora) via https://bugzilla.redhat.com/show_bug.cgi?id=572611 Importance: Unknown Status: Unknown ** Changed in: ibus (Ubuntu) Importance: Undecided => Low ** Changed in: ibus (Ubuntu) Status: New => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to ibus in Ubuntu. https://bugs.launchpad.net/bugs/1020212 Title: gtk apps keep polling for $HOME/.config/ibus/bus dir Status in “ibus” package in Ubuntu: Fix Released Status in “ibus” package in Fedora: Unknown Bug description: I've tried to do my homework but I apologize if this issue has already been fixed or if I'm reporting it to the wrong package. First off, here is my system and package info: $ lsb_release -rd Description: Ubuntu 10.04.4 LTS Release: 10.04 $ apt-cache policy ibus ibus: Installed: 1.2.0.20091215-1ubuntu4 Candidate: 1.2.0.20091215-1ubuntu4 Version table: *** 1.2.0.20091215-1ubuntu4 0 500 http://nl.archive.ubuntu.com/ubuntu/ lucid/main Packages 100 /var/lib/dpkg/status I observe that when the directory $HOME/.config/ibus/bus does not exist, *all* GTK apps poll for its creation at roughly four second intervals.

Applications that are not in use don't poll and remain dormant. It seems to have increased my laptop's battery life by about 15 minutes. The bug may have been fixed upstream (I found a Fedora bug report[1] that mentions it) but I haven't been able to pinpoint the commit.
