geany 1.36 from gentoo portage tree. When I try to open C source/header, it freezes for nearly half-minute on first such attempt. Next C file attempts go without freeze. Tried with all modules disabled. Build config (guessed from ebuild): --enable-gtk3 --enable-vte --disable-html-docs --disable-pdf-docs
My current tags database has over 2k files, which look like matching to C header files, with total size over 400Mb. On first attempt to open C source/header (but not on editor start) it loads all of them (can be visible if started with --verbose option). It doesn't matter if this file empty or just config.h, generateed by build system.
Would be better if only necessary files where loaded, based on include/import lines in opened file, recursively. Could be less annoying if geany never needed to be closed/restarted.
