qlandkartegt crashes at startup

[Hadmut Danisch]

Binary package hint: qlandkartegt

Hi,

the current ubuntu version of qlandkartegt starts only as long as no data have been under work. Once it has seen it's first map, it immediately crashes after start (obviously because of bugs in the graphic routines) with the error messages

As far as I found from comments in some forums, this is a known bug of the version used for the ubuntu package.

I just compiled qlandkartegt version 1.0, and ran into the same problem.

So maybe it is a problem of the qt library itself?

[Hadmut Danisch (hadmut)]

Just had a chat with one of the maintainers.

It happend with a particular file, which is
ftp://ftp.remotesensing.org/geotiff/samples/misc/tjpeg.tif

qlandkartegt remembers the file of the most recently opened file and reopens it on startup. So if that file kills the program, it will kill it again and again, until the path has been removed from the config file. Seems to be a bug in libgdal.

QLandkarteGT 1.7.5 and later don't crash with tjpeg.tif any more.
