Comment(by skierpage):

 In Read 49 on joyride-2273, it seems a needed library djvulibre-
 libs-3.5.20-2.fc9 is present.  And trying some of the samples at
 http://djvu.org/docs/ I had some progress but also blank pages and hangs.

 Read shows an appropriate 1 / 10 page control (good!).  But each page is
 blank (bad).  But if I zoom out from the View menu (from 230% to 192%),
 text appears (wahoo!!).  But if I zoom in again, Read and the Browse from
 which I launched it crash (bad!).  And I tried the back a page button
 after paging through a 10-page document and Sugar got so slow the mouse
 stopped tracking and I had to hold the power button down to power off
 (ouch!).  At one point `top` in a Terminal activity said Read had VIRT
 137m and RES 76m, that's pretty big memory use.  I zoomed in again and the
 mouse stopped tracking and again I had to hold the power button down to
 power off (arghh!)

 The current sort-of works behavior is pretty bad.  If my experience isn't
 an anomaly, maybe it would be better to remove the djvu mime type from the
 Read activity (as simple as editing activity/activity.info) so Read
 doesn't advertise any ability to read DjVu.  Or just leave things as they
 are and caution that DjVu viewing has lots of bugs.
