--- Comment #3 from Larry <Larry at Oisher.Net> ---
I found no relevant differences between 2 Fedora 20 workstations, one
exhibiting the problem and the other not, both with  the same package versions.
 I executed Okular on both with strace output to files and compared them.  The
only significant differences begin at line 16219 in the attached strace log
(uploaded) where there is a nearly constant stream of "recvfrom" errors,
probably in a message loop but you would know better.

I'm not sure if it's relevant but I did notice  many occurrences of blocks of
code "swapped" between what should have been similar(different only by memory
addresses or file descriptors) log files.  Especially when the blocks of code
were reading libraries or configuration files.  The return values of the
various file-existence checks were consistent but the 2 traces would then read
or check blocks of files in different order.  For example, the block of code in
lines 546 through 553 occurs on the failing machine prior to the block of code
in lines 554 throu 568 whereas it occurs on the working machine prior the
second block.

Perhaps you can see an obvious cause for the problem that I don't.

Thanks for your time and attention.
