http://bugs.darcs.net/issue844 Some versions of darcs misuse gzip, causing checksum corruption. The corrupt gzip files can be "fixed" by recalculating the CRC; the attached heal-darcs.sh shows one such solution. This corruption affects many (most?) CL darcs repos. It usually doesn't affect darcs itself (which ignores the checksums) but often causes problems with other tools. I used to notify people of this issue, but now just run heal-darcs and hope mismatched checksums weren't actually valid. - Daniel
