OK, it crashes on version check:
deejay1@sulaco:~/tilesAtHome$ pngnq -V
Segmentation fault (core dumped)

I have the same problem, pngnq crash on version check (tiles@home, svn rev 9242, hardy amd64).

I've tried with the fix proposed on the related debian bugs (http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=491860), it fix the problem for me.

after rebuilding the package (with the fix), pngnq -V shows:

dex@anne:~$ pngnq -V
pngnq 0.5
   Compiled with libpng 1.2.15beta5; using libpng 1.2.15beta5.
   Compiled with zlib 1.2.3.3; using zlib 1.2.3.3.

Thanks for reporting this, since the fix is quite trivial I'd suggest we wait until this is fixed by debian and sync. If this will not be done before freeze we will make it as an ubuntu specific change.

[Łukasz Jernaś (deejay1)]

Here's a debdiff - just in case ;)

I will be able to upload a fixed revision to Debian only on Saturday.
Probably the freeze won't happen before Saturday, right? :-)

Best regards,

Hi Nelson, don't worry, we have plenty of time ;-)

Hi!

I have uploaded a new revision to Debian, so you can sync from it now :-)

Best regards,
