Search for regex throws exception

[AM909]

Choose Edit->Search. Enter "\+=*" (without the quotes) in the search string box. Check "regular expression". The following exception occurs. This _is_ a valid regex AFAIK (looking for a tag where k=+, with any value). Also it seems that this exception should be caught and presented to the user with a normal app error dialog.

Correct search would be "
+:.*" You need to escape the \ in josm. Fixed the wrong esception in r3303 and r3304.
