digiKam Freezes when Right-Click a Tag

I am not sure what is happening. (I am just a user as well).
You are free to choose digiKam version and OS for sure.
Hopefully you have a chance to get bug traces and send them to digiKam developers before you quit Mint and dk6.4.

On Linux:

If you installed digiKam from your distribution repository:

  1. Make sure GDB is installed (http://sources.redhat.com/gdb/)
  2. Open terminal and run:
    2.1 gdb digikam
    2.2 (gdb) catch throw
    2.3 (gdb) run
  3. Proceed to step # 4 described below

If you use official appimage:

  1. Open terminal

  2. Launch your appimage with debugoption in the end, e.g.
    ./digikam-6.2.0-x86-64.appimage debug

  3. Proceed to step # 4 described below

  4. If digiKam crashes, you will get to the GDB command prompt. If digiKam “just” freezes, press CTRL-C to get to the GDB prompt. Once you are at the prompt, use the bt command, copy the backtrace and exit GDB as shown here:
    4.1 (gdb) bt
    4.2 (gdb) the_backtrace_is_here
    4.3 (gdb) quit
