[Chromium-dev] 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 Debug(alpina:22242): calling crNetConnectToServer( "localhost", 10000,

CR Debug(alpina:22242): No tiling information for server!
CR Warning(alpina:22242): It looks like there are nothing but file
clients. That suits me just fine.
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

#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,

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.
