Dear Maintainer,

   * What led up to the situation?
   - I was unable to use the flashtool from Flashtool.net due to "outdated"
     glibc in Debian buster. I fell back to the Debian package version
     which I did not know of until then. Using the Debian version seemed
     like the best solution to me.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   - I tried to flash a Sony Xperia Z2 Sirius stock ROM via Flashtool.
   - The good:
   	- gui: started
	- connection to the device via USB in flashmode/fastboot was
	  possible
	- flash preparation could start but: it is known, or at least
	  was known, that the linux version needs an external Xperifirm
	  version to download the needed firmware. So I used Xperifirm,
	  via mono, to fetch und unpack the needed firmware (worked) and
	  loaded it to ~/.flashTool/firmwares/downloads to build the
	  flash-list via the "XF-Button" in flashtool.

   * What was the outcome of this action?
   - Nothing happend, there was no list build and therefore the flash-preparation
     could not start nor be finished, the software did nothing.
   - This is reproducible
   - I used an old version of Flashtool to build a flash-list and
     afterwards could proceed to the flash-preparation where the
     software finally fully hung-up and did nothing more

   * What outcome did you expect instead?
   - I expected that the flash-preparation would finish and I will be
     asked to conncet my device in flash-mode and then would get my
     device flashed. This did not happen.
   - I added the terminal output
