Description Radomir Dopieralski 2009-02-17 19:17:26 CET
User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9.0.6) Gecko/2009020518 Ubuntu/9.04 (jaunty) Firefox/3.0.6
Build Identifier: Thunar 0.9.99.1

I often have to create very large graphical files (A3 at 1200dpi, for example), and I've noticed that each time I save or copy/move such a file, Thunar statts two instances of /usr/lib/thunar/thunar-vfs-pixbuf-thumbnailer-1 to (re)generate the thumbnail -- which effectively renders the computer unresponsive for several minutes. It would be nice to have some option to never automatically generate thumbnails for files larger than certain size. Another improvement would be to start the thumbnailer processes with low prority.

Reproducible: Always

Steps to Reproduce:
1. Create a large graphics file
2. Save it to the disk
3. Wait until you can do anything again
Actual Results:  
The computer is nearly frozen as both CPU cores are busy generating the thumbnail.

Expected Results:  
The thumbnail is only generated upon request for large files.

This can also be done just with a low-priority process.

Using Thunar 1.6.2 / XFCE 4.10 / Gentoo.

I plugin my PTP camera. Shows up in Thunar under devices.

I click the folder with images / video files on camera. Thunar now HANGS ITSELF for 4-5 minutes (depending on how much is there) reading and reading the camera to show thumbnails.

Edit -> Preferences -> Show Thumbnails is set to "Local devices only". I do not consider removable camera a "device".

I would very much like thunar to please not consider removable devices as local devices.

A temporary solution I've found is to set Edit -> Preferences -> Show Thumbnails to never before I connect my camera. That prevents thunar from hanging for ages and copying files also seem to go a whole lot faster. I suspect that thunar may be trying to make thumbnails while copying files, if so then that should also be fixed somehow (I think the thumbnailers are seperate processes, so I don't know how that would work).
