I just wanted to call everyone's attention to this bug:
http://www.lyx.org/trac/ticket/8854
It appears to be a very nasty dataloss bug in 2.1-beta1. What seems to
be happening is that, on save, the LyX file is corrupted in very weird
ways, with random parts of the file being replaced by things like
"mathnorma" or "Plain La"---fragments of things that do make sense in
other contexts.
A report of what looks like the same bug in 2.0.6 is here:
http://tex.stackexchange.com/questions/134009/lyx-inserts-and-removes-words-randomly
That was on Windows, as well, whereas #8854 is on Ubuntu. Another
difference is that #8854 seems to show up only on export. The original
report was of corruption in the exported 2.0 file, but by looking in the
temporary directory we found that the 2.1 file was already corrupt. That
makes it sound as if the problem has to do with background export. But
the 2.0.6 report seems to concern just saving the file and not export.
The reporter has done some excellent work to help us figure this out,
but neither Pavel nor I have been able to reproduce---though the
reporter sees it all the time. It would really, really help if someone
could manage to reproduce this.
Obviously, it would also help if someone has a good idea what might
cause this.
