I have a problem with my website, which is completely gzipped:

http://goout.cz/cs/ - its validation works correctly

http://goout.cz/cs/fotoreporty/ - validation fails

When I try
curl -v http://goout.cz/cs/fotoreporty/ | gzip -d
I am getting expected results. But validation on

http://validator.w3.org/check?uri=http%3A%2F%2Fgoout.cz%2Fcs%2Ffotoreporty%2F#fatal-errors

yields:

The error was: Can't gunzip content: Header Error: Minimum header size is 10 bytes

The gzip header seems to me okay to me:

$ curl http://goout.cz/cs/ | head -1 | hexdump | head -1
0000000 1f 8b 08 00 00 00 00 00 00 00 ed 5d cd 73 db 38

$ curl http://goout.cz/cs/fotoreporty/ | head -1 | hexdump | head -1
0000000 1f 8b 08 00 00 00 00 00 00 00 ed 7d cf 73 e3 46

Am I doing anything wrong? It seems to me the problem must be on the Validation side.

Thanks
