[josm_report@…]

What steps will reproduce the problem?

1. bug in tag preset file ( In this case a <key text="" instead of <key value="" )
2. add tag preset file in previous version of JOSM
3. update JOSM
4. select map item that matches buggy tag preset entry

What is the expected result?
Tell user of tag preset bug, as attempting to add the tag preset file in current JOSM does.

What happens instead?
Unspecific bug dialog.

Please provide any additional information below. Attach a screenshot if
possible.

I cannot reproduce. Please attach a small buggy preset to ease debugging.
