Description Florian 2010-07-07 16:26:36 UTC 
man-db 2.5.7 crashes when asked to display uncompressed manpages in languages other than English.

The error message is :
man: man.c:2401: display: Assertion `decomp->ncommands == 1' failed. Aborted


Reproducible: Always

Steps to Reproduce:
1. Disable portage automatic compression in /etc/make.conf with :
PORTAGE_COMPRESS=""

2. Enable installation of some localized pages in /etc/make.conf :
LINGUAS="en fr"

3. Unmerge sys-apps/man (it blocks man-db) :
# emerge -ca sys-apps/man

4. Emerge man-db :
# ACCEPT_KEYWORDS=~x86 emerge -av =sys-apps/man-db-2.5.7

5. Try to display man-db own manpage :
$ LANG=fr LANGUAGE=fr man man
Actual Results:  
man: man.c:2401: display: Assertion `decomp->ncommands == 1' failed. Aborted

Expected Results:  
It should have displayed the manual.


Workarounds (choose any of) :
1) do not disable compression
2) use an english-only configuration
3) stay with the good old sys-apps/man

I found on linuxfromscratch.org[1] a patch for this issue. I modified it to have it working on Gentoo.

Here is a diff for man-db-2.5.7.ebuild (it adds the needed "epatch" line)

Bye.

i'm sure Colin will be interested in the patch
Comment 6 Colin Watson 2010-08-23 08:57:22 UTC 
The patch is a backport from latest bzr.  I agree that you should apply it.  I'm hoping to get round to a 2.5.8 release relatively soon but haven't managed to carve out time for it yet.
Comment 7 SpanKY gentoo-dev 2010-08-23 09:16:50 UTC 
thanks ... wasnt aware it was already upstream.  wanted to make sure it was.

added to 2.5.7-r1
