gpick v0.3 compil fail on Archlinux

[PowaBanga]

Hi everybody,
gpick crash on start on my archlinux :

/usr/include/c++/12.1.0/bits/basic_string.h:1280: std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::reference std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::front() [with _CharT = char; _Traits = std::char_traits<char>; _Alloc = std::allocator<char>; reference = char&]: Assertion '!empty()' failed.
[1]    5307 IOT instruction (core dumped)  gpick

does anybody know why ?

ok on archlinux, gpick is actualy on v0.2.6.
Compil of the v0.3 fail... after read this #209 (comment) i created my own PKGBUILD on the V0.3 release with my diff to patch in, and it worked !
