Some time ago i've installed SQL Explorer plugin, which caused Aptana to hang on it's (SQL Explorer) opening. I've purged it, but since then workspace may become corrupted and whole application hangs when i try to open internal Aptana explorer or App Explorer. Only solution i've found is to create a new workspace, but new workspace may corrupt as well. I can't tell for sure if this is really connected with sql explorer or just with environment.
I'm attaching the .log file from corrupted workspace, hieroglyphic-alike message near ruby create-process error is wrongly encoded 'file not found' in russian.
