applications crash upon entering directories with cyrillic named files

[Alexandre Prokoudine]

Any gtk2 based application crash when it enters a directory that has cyrillic letters in its name or just file with cyrillic letters inside. E.g. bluefish crashes when I try to open a file in such a directory via 'open file' dialog, and Nautilus restarts when I enter such a directory.

It happens on both a clean installation of DapperFlight2 and dist-upgraded version of it.

Thanks for your bug. Could you get a backtrace of the crash (the bug-buddy dialog has it)? Probably a duplicate of #28640

[Alexandre Prokoudine (alexandre-prokoudine)]

Would Inkscape count for example? :)

As soon as I enter such a directory, it crashes with:

Program received signal SIGSEGV, Segmentation fault.

Thanks for your bug. That's a known libc issue, you can workaround it by setting LC_COLLATE=C by example

[Sebastien Bacher (seb128)]

And thank you for the backtrace, the wcsxfrm_l() to start shows it's that libc issue I pointed before

[Alexandre Prokoudine (alexandre-prokoudine)]

"That's a known libc issue, you can workaround it by setting LC_COLLATE=C by example"

Thank you for advice. How exactly can I do it, so that all applications benefit from it, not only those I run from console where I set the variable before?

[Sebastien Bacher (seb128)]

setting LC_COLLATE=C to /etc/environment should do the trick
