Hi,

I discovered something.
It looks like problem is caused by empty line in booting command list:

...
script/lexer.c:305: token 290 text [Debian GNU/Linux, linux
2.6.32-bpo.5-686
/dev/sdb1]
script/script.c:50: malloc 0x3ffac100
script/script.c:50: malloc 0x3feddab0
script/lexer.c:305: token 290 text []
script/script.c:50: malloc 0x3ff11360
script/script.c:50: malloc 0x3ff14ee0
script/script.c:163: arglist
script/script.c:50: malloc 0x3ff1e4a0
script/lexer.c:305: token 259 text [
]
script/script.c:50: malloc 0x3ff24e90
script/script.c:50: malloc 0x3ff25010
script/script.c:198: cmdline
script/script.c:50: malloc 0x3ff2d2c0
script/lexer.c:305: token 0 text []
script/script.c:50: malloc 0x3fee1d10
script/script.c:50: malloc 0x3ff11340
script/script.c:294: append command
script/script.c:50: malloc 0x3ff1b130
unaligned pointer 0x692a6373

But I don't know where the empty line is generated - it is not in
grub.cfg

Regards
Ales
