 Often have the frontend crash when entering a netvision channel.
 This seems to be caused by something in the paththumb download.
 If I update the database to set all the paththumbs of the channel to be
 the same local file image no crash.
 Also after a few crash if all the paththumb images are download and are in
 the cache then also no crash.
 Looks like mostly occurs for channels where there are many directories
 (~10 or more)
 Downloading of video thumbnails do not cause a crash.

 Downloading of the paththumbs looks quite strange. Starts with no images,
 then images blink on and off as they download, then when all are
 downloaded, all the images pop up.

 See lots of the following errors in frontend log
 QString::arg: Argument missing: "images/image_gallery_no_image.png" , 1
 QString::arg: Argument missing:
 "/home/auric/.mythtv/thumbcache/thumbnail_37530_15694.gif" , 1

 Have also seen a couple of freezes, but it is usually a crash.
 I think the freezes give the following error. (Could be from a crash, can
 do more testing if needed)
