In the meantime – after hours of debugging and patching – I made some
success: The splash screen is shown, then the screen becomes black,
after some minutes becomes blue for a few seconds and becomes black
again. (I'm using a VM, thus everything is a bit slower than usual :-)

I'm using an adopted "startkde" script to set QML_IMPORT_TRACE and
QT_DEBUG_PLUGINS to get more information and collect the output and
strace-output. According to this output, most things look fine, there is
now serious error message.

I would appreciate if somebody could give me some hints whether these
messages are relevant and if, where to look at further (e.g. which
program is causing this.)

In the strace-output I found the following irritating entries:

  * kdeinit5 (or one of its wrappers) tries to access
    "lib/libkdeinit5_/klauncher.so". Mind the slash after the
    underscore. I did not find and place where this could happen.
  * In libkdeinit5_kded5.so ( I assume there are repeated lstat-calls to
    "kcminit" without any path and IMHO bound to fail:
  * mkdir("/root/.cache", 0777)             = -1 EEXIST (File exists)
    stat("/root/.cache", {st_mode=S_IFDIR|0755, st_size=120, ...}) = 0
    open("/root/.cache/ksycoca5_en_0F2dH4OuzLnJNdnBPRVU_FLbrSk=.lock",
    O_WRONLY|O_CREAT|O_EXCL|O_CLO
    open("/root/.cache/ksycoca5_en_0F2dH4OuzLnJNdnBPRVU_FLbrSk=.lock",
    O_RDONLY|O_CLOEXEC) = 9
    stat("/proc/version", {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
    readlink("/proc/532/exe", "/gnu/store/…"..., 4097) = 69
    lstat("kcminit", 0x7ffe82b272d0)        = -1 ENOENT (No such file or
    directory)
    open("/gnu/store/…-tzdata-2017b/share/zoneinfo/Europe/Paris", O_R

Thanks for any help
