Description Jason Madden

2006-04-10 13:59:22 EDT

I have a project with a folder containing Oracle source files. These files have extensions of .pks, .pkb and .sql. Until I added explicit Eclipse file associations for each of these, attempting to expand the folder (in the Navigator view) containing these files would hang the entire UI. (Other files seem to have a similar problem). Associations set in the Gnome file manager don't seem to make a difference, only Eclipse associations. 

Here's a stack trace from 3.2-M6 running on Gnome 2.12.0. Filed under SWT because of the top stack frames:

If that GNOME call is hanging I am very tempted to say there is
something fundamentally wrong with your GNOME setup. What
happens when you browse to that folder in nautilus? What
distribution are you using?

That's what my first throught was, too, but I'm unable to find anything wrong. Opening the folders in Nautilus happens instantly, and the files all have reasonable icons. All three of those file extensions are associated with vim, though I tried changing Nautilus associations during the course of tracking this down (Other options Nautilus presents are "Text Editor" and "Word Processor" IIRC). 

This is on Gentoo.

Is this still reproducible in Mars?

No response in awhile, closing this ticket now. The stacktrace isn't even reachable anymore as GNOME code is gone.
