Bug#730327: kstars: FTBFS w/o writable HOME: tests fail

["Aaron M. Ucko" <ucko@debian.org>]

Source: kstars
Version: 4:4.11.3-2
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Builds of kstars in environments without writable HOME directories (as
on nearly all autobuilders) have been failing:

  1/2 Test #2: FixedWidthParserTest .............***Failed    0.06 sec
  trying to create local folder /sbuild-nonexistent: Permission denied
  trying to create local folder /sbuild-nonexistent: Permission denied
  testfwparser(896) TestFWParser::TestFWParser: "Couldn't
  open(/sbuild-nonexistent/.kde/share/apps/kde/TestFW.txt)" 
  testfwparser(896) KSParser::KSParser: Unable to open file:
  "/sbuild-nonexistent/.kde/share/apps/kde/TestFW.txt" 

Please try running the test suite with HOME set to a directory within
the build tree created for that purpose.

Thanks!
