OK, then that is definitely related. LyX won't see the one in
.lyx/layouts if there is one in the document directory with the same
name. At least, there are circumstances under which it won't use it.
What happens, I think, is that
One more thing that might provide a hint. At least some of the
times I
observed this automatic switching away from my custom document
class,
when I scanned the list of available document classes to "put it
back",
my custom document class was listed twice in the document class.
This
document class switching is intermittent, and while I can't say
for sure
a correspondence between it appearing twice and it evaporating, I
cannot
remember a time it disappeared when it was not listed twice, and I
cannot
remember a time when it did not disappear when it was listed twice.
This is again a consequence of using the local layout. It's listed
twice
because one of them is the local layout and one of them is the system
version. See my post to the devel list for ideas about who this could
have caused the problem.

Thanks Richard,
I doubt it's that simple, because I've been using the exact same
layout in
book dir, symlink in /home/slitt/.lyx/layouts since "Troubleshooting
Techniques of the Successful Technologist" in 2001, and the problem
did not
routinely occur. Furthermore, I'm using it right now, and right now
the
problem is not occurring. There must be other factors, and right now
I just
don't have the time to investigate this intermittent. I'm trying to
get my
new book out this week. However, if I see it happen again, I'll try
to get
every bit of information I can.
I guess this behavior is new to Lyx 1.5.x and you probably did use LyX
1.3.x by the time :-)
Richards answer also explains a related problem I had a couple of
days ago: As Steve, I had a layout side by side to my master
document, but also sym'linked from my .lyx/layouts directory. (Before
Lyx 1.5 this was basically the only way to maintain the layout
together with the documents in a source control system such as svn.)
The actual chapters are input'ed as child documents into the master
lyx file. On disk, they are located in a "part" subdirectory. When I
tried to compile the master (I had not done so for many weeks, so this
was the first time trying it with 1.5), I got a lot of funny error
messages; something similar to:
"ERROR: Layout 'thesis' used by child document is incompatible to
layout 'thesis' used by master document"
It took me quite a while to figure out that LyX uses the side-by-side
layout file for the master, but the one from .lyx/layouts for the
children and that this caused the problem. (I would consider this as a
bug, as both layout files were actually identical, so not incompatible
at all!)
I solved the issue by renaming the layout file so it is no longer
considered as one by LyX and all files (master and children) refer to
the same layout in my .lyx/layouts folder.
