[M-Dev] Crashing message

[Xavier Nodet]

Hi all,

the attached message triggers a crash in wxHtmlTagsCache::QueryTag.  I
changed this method as the attached patch against WX_2_6_1 shows (I took
the simplest route, and did not change the API).

Note that the message has a web-bug in it.

Have a good day...
