MKVToolNix GUI: under certain circumstances the GUI would try to display error messages from a secondary thread, which isn’t allowed in Qt, causing to program to either hang or outright crash.Now they’re assigned sequentially in the order the tracks appear in the destination file again. mkvmerge: track numbers in the destination file were assigned out-of-order when the track order in the source files differs from the one in the destination file.mkvmerge: sorting tracks by type did not work properly when some tracks weren’t copied.This fixes the programs not catching an exception from the boost::filesystem library which doesn’t cope with mis-configured locale systems well. If neither of the three succeeds, an error message will be shown, and the program will abort. if environment variables such as LC_ALL have been set to fr_FR.UTF-8 but the locale for fr_FR.UTF-8 hasn’t been built, MKVToolNix will try to fall back to en_US.UTF-8 first & C.UTF-8 second. all: Linux: if initializing the locale system based on the system’s settings fails, e.g.

Also added an installation check for the same issue. This fixes some installation issues that could occur when a user extracted a portable app archive into a folder like C:\Program Files\MKVToolNix.

The Windows and macOS binaries as well as the Linux AppImage are available already. You can download the source code or one of the binaries. Fortunately they were only annoying but didn’t affect existing files. MKVToolNix v78 is out with tons of bug fixes, especially for those crashes in the GUI’s header editor & for the GUI hanging when adding files via drag & drop.
