MySQL Bugs: #70786: MySQL Workbench editor uses up all memory and crashes

Bug #70786	MySQL Workbench editor uses up all memory and crashes
Submitted:	31 Oct 2013 12:44	Modified:	12 Nov 2013 12:57
Reporter:	Halil –zgr	Email Updates:
Status:	Unsupported	Impact on me:	None
Category:	MySQL Workbench: SQL Editor	Severity:	S1 (Critical)
Version:	6.0.7	OS:	Linux (Ubuntu 13.10 AMD64 )
Assigned to:		CPU Architecture:	Any

Description:
I've first tried the one in the official apt repository (5.2.47+dfsg-2). It was using up all the memory in the editor pane as soon as I first hit Ctrl+Space in order to get auto complete. I've removed it and tried the one at MySQL downloads (6.0.7). It crashes the same way (as soon as it opens that last saved editor pane).

Command line output
-------------------
$ mysql-workbench
Ready.

What's dconf worker?

Please try building WB for Ubuntu 13.10 by yourself, maybe it will work better. Our packages don't support 13.10 yet.

dconf worker was in the syslog, I don't really know what it is.

I'm not a regular source builder and hence I couldn't get the build working as per instructions at http://mysqlworkbench.org/contribute/mysql-workbench-linux-build-instructions/ for mysql-workbench-community-6.0.8-nodocs-src.tar.gz (Generic Linux (Architecture Independent)).

I'm having the same problem, version:
MySQL Workbench CE (GPL) 6.0.9 11421  build 1170
