[Bug 188211] [NEW] kcalc crashes with X^Y operation

[sko]

Public bug reported:

Binary package hint: kcalc

kcalc crashes (segfault) with more-or-less simple operations like X^Y.
I could reproduce this by:
  Type: E (choose from constants -> mathematics -> E (euler's constant))
  Click: [X^Y] button
  Type: PI (choose from constants -> mathematics -> PI)

(calculate e^pi)
and say hello to the KDE crash dialog... (see below)

(the good old xcalc has no problems with this)

KUbuntu version: 7.10 (gutsy) with KDE 3.5.8

Here is the stackframe:
