more information in backtraces

[Dominik Haumann]

Hi,

in Kate, we have a (virtual) Cursor class:

class Cursor
{
  // public functions

  private:
    int m_line;
    int m_column
};

Unfortunately, in backtraces by Dr. Konqi we only get:
#11 0x00007f1c85128b2a in KateLayoutCache::updateViewCache (this=0x54db630, startPos=..., newViewLineCount=35, viewLinesScrolled=<optimized out>)

Here, startPos is a Cursor, but we cannot see its values.

It would help tremendously sometimes to know the line/column values. So
having "startPos=(4, 2)" instead of "startPos=...".

Is there any way to provide this feature to get better backtraces by
default in Dr. Konqi?

In gdb itslef, there are addons that already provide some pretty printing
through KDevelop:

Maybe this can be reused?

Thanks,
Dominik
