Cannot "Grab" anything (*** Remote sawfish error...)

[janemba <cap janemba gmail com>]

Hello,

I'm sorry to contact you but I have the same problem in two sawfish
different installation. I tried to search on the internet and on the
IRC chan but anybody know how to solve my problem.

When I use 'sawfish-ui' in 'Matched windows' tab, I click on 'Grab'
button and nothing happen. In my console I have this message :

*** Remote sawfish error: (missing-arg #<subr eval> 1)

So I strace sawfish-ui and here is the interesting thing :

socket(PF_FILE, SOCK_STREAM, 0)         = 5
connect(5, {sa_family=AF_FILE,
path="/tmp/.sawfish-thomas/icetea.WORKGROUP:0.0"}, 44) = 0
write(5, "\0", 1)                       = 1
write(5, ".\0\0\0", 4)                  = 4
write(5, "(nokogiri-grab-match-window-prop"..., 46) = 46
read(5, "\35\0\0\0", 4)                 = 4
read(5, "\2", 1)                        = 1
read(5, "(missing-arg #<subr eval> 1)", 28) = 28
close(5)                                = 0
gettimeofday({1191255328, 973554}, NULL) = 0
select(7, [6], [6], NULL, NULL)         = 1 (out [6])
writev(6, [{"+\7\1\0", 4}], 1)          = 4
select(7, [6], [], NULL, NULL)          = 1 (in [6])
read(6, "\1\2E\"\0\0\0\0\352\0\300\0\0\0\0\0\0\0\0\0H\222\346\277"...,
4096) = 32
read(6, 0x808de00, 4096)                = -1 EAGAIN (Resource
temporarily unavailable)
fstat64(1, {st_mode=S_IFREG|0600, st_size=476094, ...}) = 0
mmap2(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1,
0) = 0x4007b000
write(1, "\7", 1^G)                       = 1
write(2, "*** Remote sawfish error: (missi"..., 54*** Remote sawfish
error: (missing-arg #<subr eval> 1)) = 54
write(2, "\n", 1
)                       = 1


the file "/tmp/.sawfish-thomas/icetea.WORKGROUP:0.0" exist and sawfish
can connect to it but after this it tries to read and write onto it.
It tries to retrieve an argument I think. But the result is the
message I poste above. I check the permission of the tmp file and it
seems ok. But when I tried to "echo" something on it or to "cat" it I
have this error : " no such device or address".

At the beginning I think it was an X problem then I tried #xorg channel on
freenode and the results was this file isn't created by X.

I don't know what is the problem exactly and I hope than you can help me.

Regards,
