Eclipse/LiClipse freezes when .py file is opened

My LiClipse with PyDev started freezing several seconds after project is open. I've checked for updates without success. When it is freezed, LiClipse consumes about 48 percent of CPU and 300 000 kb of memory (consuming so much memory is probably ok).

EDIT: It freezes when the project is NOT RUNNING, it is just opened in Eclipse!

I've already tried to remove .metadata and import projects from scratch but this problem has occured again.

I've a suspection that this freezing occures when I have opened one specific py file where there are a very long strings (I'm handling with requests - posts).

Here is a piece of log from .metadata but It don't contains probably the issue of freezing according to time (last logged issue - 15:56, last freeze - 15:58):

Unfortunately the log doesn't seem to help much (the entries shown should be harmless).

I think you're right in that there's probably some pattern in the code which is making it recurse for some reason, so, if it's public, can you point me to it so that I can try to open it to reproduce/fix the error?

Otherwise, an alternative could be attaching some profiler to Eclipse when that happens and pass me the output from it (i.e.: https://www.yourkit.com/ can attach to a running program if you pass some vmargs to eclipse.ini -- https://www.yourkit.com/docs/80/help/agent.jsp)

Another option could be getting the Eclipse SDK, the PyDev source code (http://pydev.org/developers.html) and then do a debug session and press the debugger pause to see what may be happening...
