[Mono-list] Corrupted Linux generic installer image (1.2.5.1) ?

[Adrien Dessemond]

Hello !

When I try to run it (a chmod 700 has been done on it),the process
seems to exit immediately with no error messages like "segmentation
fault" being printed, just as it did nothing.

A strace reports this :

Doing a 'file' reports : 

file ./mono-1.2.5.1_0-installer.bin 
./mono-1.2.5.1_0-installer.bin: ELF 32-bit LSB executable, Intel 80386,
version 1, statically linked, corrupted section header size

Retried the download many times, nothing is better but the MD5 sums
matches the one given on the FTP site. If I am the one with the
trouble, a long saturday seems to be ahead of me :-) At worst, I will
rebuild from the source.

Anyway, good piece of work guys !
