Non-breaking space (doubled) bug

It's a puzzler!

I think I'm going to go through your list of "prime candidate" shared libraries and see if I can find any on the Debian machine that are older than versions present on my build machine, and start from there.

That sounds like a good idea. You might want to go and use Doitsu's full list in case I threw out the culprit by mistake in my first pass.

Thanks!

I take it back! It IS libxml2.

I tried to copy a newer version of libxml (2.9.1 from Linux Mint 16) to my Debian Wheezy sigil install, but of course that won't work because of glibc dependencies that that Sigil executable can't meet. So just for laughs, I copied the older libxml2 library (v2.7.8) from my Mint 12 (Ubuntu 11.10) build machine, and lo and behold, the damn thing works! The doubling issue goes away!

Could the 2.8.0 version of libxml2 on Wheezy just be a buggy version?

It'd be no problem to include the older 2.7.8 version with the binary package (the LD_LIBRARY_PATH is already being set) ... but that won't help Wheezy users who might want to build Sigil on their own. Nor would I want to trump newer (and working) versions of libxml2 on newer systems.

Maybe I'll just create a separate, special binary package for Debian Stable and write Wheezy off as insufficient for building Sigil for now. Once Debian Stable moves beyond libxml2 v2.8.0, the problem may fix itself.

Hi DiapDealer,

Glad you found it! It may be a bug in that one release or alternatively, it could be a Debian packager bug as packagers often add in their own patches , or it could be that the Qt version of libxml2 that Qt was compiled against conflicts with that one 2.8.0 version you have. I looked in the change log on the libxml2 site between 2.7.8, and 2.8.0, and from 2.8.0 to 2.9.1 but could not see a specific change that might have caused the problem.

Nice work!

Kevin

IMHO, it's not worth spending too much time on this since the next Debian release, "Jessie," is expected to be released late March and will come with version 2.9.1. of libxml2, which should be sufficient.
For the time being, I'd recommend to simply mention this issue in the Unofficial Sigil Ubuntu-ish binary packages thread.
