Opening VM Settings dialog can hang (infinite loop) if column is narrow

Description
After upgrading to virtualbox 5.2.0-1 I found that opening Settings for any VM would hang the VirtualBox process (100% CPU usage). Deleting local settings, recreating VMs, etc, did not help with this.
After building the SVN trunk locally I found that it was infinite looping in SFTreeItemView::processColumn(). The "strOneString" variable had become an empty string (iTextWidth == 0) but as iIdentSize > cWidth, the loop condition was always true.
I believe this bug can always be triggered if the column has been resized to a low width (ie if cWidth has a low value) and if m_enmFormat == FormatType_EllipsisEnd. Possibly under other conditions as well.
Simple patch to break out of the loop if iTextWidth == 0 attached. This fixes the problem for me.

Looks like this has been fixed in SVN now:
