Two (probably unrelated) problems with FileClients

Using the config script at the end of the email, under cr-1.6 I am able to
play back OpenGL traces I have made from various applications.  Under 1.7
I get the following output:

CR Error(alpina:22242): Assertion failed: mural->numExtents > 0, file
server_tiles.c, line 530

Which terminates with SIGTERM, and here's the backtrace:

#0  0x40277ac1 in kill () from /lib/libc.so.6
#1  0x4038f9ed in pthread_kill () from /lib/libpthread.so.0

#9  0x40263d06 in __libc_start_main () from /lib/libc.so.6

That's the first problem.  I can't seem to replay any traces under
1.7.  Have others had issues with FileClients under 1.7?

The other problem concerns a particular trace.  Same config file.
cr-1.6.  Here's the output:

CR Warning(alpina:22216): It looks like there are nothing but file
clients.  That suits me just fine.
CR Warning(alpina:22216): Couldn't open X display named '-2147414829'
CR Warning(alpina:22216): Couldn't get a visual,
renderspu_SystemInitVisual failed
CR Warning(alpina:22216): headSpu.CreateContext failed in
crServerDispatchCreateContext()

crserver terminates with SIGSEGV.  Here's the backtrace:

#0  crServerDispatchLoadMatrixf (m=0x417e7478) at server_projmatrix.c:23
#1  0x40123dc3 in crUnpackLoadMatrixf () at unpack_matrices.c:40
#2  0x40120500 in crUnpack (data=0x56, opcodes=0x417e70ab,
num_opcodes=131,
    table=0x417e7050) at unpack.c:1756
#3  0x080549a8 in crServerSerializeRemoteStreams () at server_stream.c:290
#4  0x08049fe8 in CRServerMain (argc=134960048, argv=0x810d408)
    at server_main.c:188
#5  0x08049ea9 in main (argc=1, argv=0xbffff764) at main.c:11
#6  0x4022bd06 in __libc_start_main () from /lib/libc.so.6

crServerDispatchLoadMatrixf tries to access
cr_server.curClient->currentCtx->transform.matrixMode, but
cr_server.curClient->currentCtx is null, as CreateContext failed.

If anybody can provide any input on this I'd be very grateful.  I've been
beating my head against it for a while now.  Also, I'd be happy to supply
traces if they are needed.
