Description koniszcze 2013-02-28 08:17:08 UTC 
NetBeans IDE freezes while trying to open/parse HTML file. The file is standard HTML, but it contains PHPTAL template engine tags.
The other HTML+PHPTAL files I'm editing seem to open normally.
I'm unable to generate memory snapshot as IDE hangs completely, taking 100% CPU.

The end of messages.log is filled with following lines:

Please attach the file. I can do nothing w/o it. Thank you. The messages are likely unrelated. BTW you may take several threaddumps in the console, that would be almost as good as the snapshot.
