Intellij Idea12 Failed to clear URL cache

Question

I just installed ubuntu 13.10 x64 on my laptop, i proceeded to install Intellij Idea12, which is running perfectly on my 32bit system, both machines having java 1.7.0_45 from oracle. When i run Idea.sh on the x64 from the terminal i get:

Java HotSpot(TM) 64-Bit Server VM (build 24.45-b08, mixed mode)
Failed to clear URL cache

If i run it as sudo i get the same output but it starts, tho i would really like to know what the issue is, i have invalidated the caches (Files->Invalidate caches) with Intellij-Idea started as sudo, and also removed all the caches manually but the problem persists.

Thanks in advance.

You may already have one instance of IDEA running. Go ahead and check:

$ ps -ef | grep idea

Use kill or kill -9 to stop that instance then try restarting it.
