I just tried to export/import my inspection profiles to another machine, both running 7274 EAP, but it didn't work. The export went find, and if I manually examine the settings.jar the inspection profiles are in there. But when I try import them into IDEA on the othe rmachine, nothing happens. There are no errors in IDEA's logfile.
It looks like there is a Jira on this issue, although it is marked as Medium. This should be HIgh since it is a big regressoin. It looks the whole import feature is busted.
Import Settings does not work
