Currently, Openfire does not process IQ-get requests when the IQ stanza has no 'to' address (it does process similar IQ-set requests though). This is reported to have causes problems http://codingteam.net/project/jappix/forum/show/4442.
Removing the 'fix version' for all unresolved issues that were scheduled for version 7.8.2. We're releasing this version today - the remaining issues should be rescheduled later.
fix appears to have gone in for 4.1.0, can reopen if this still needs work
