Geogebra does not draw tangents

[Christoph Werthwein]

geogebra 3.2.47.0+dfsg1-1, Ubuntu Precise

When i try to draw a tangent to a curve (sin(x) in this example), Geogebra reports

*** BEGIN Message from [geogebra.cas.GeoGebraCAS.evaluateMathPiper] at 11:23:13 free memory: 44536KB
String for MathPiper: D(x) Sin(x)
Exception from MathPiper: Error encountered during initialization or parsing: Error parsing expression, near token Sin.
*** END Message from [geogebra.cas.GeoGebraCAS.evaluateMathPiper] at 11:23:13 free memory: 44536KB

and fails to draw a tangent.

Geogebra 4.0.19.0+dfsg1-3 fixes this bug in Debian unstable (actually, the real fix is upgrading mathpiper to 0.81f+svn4469+dfsg3-1; geogebra 4.0.19.0+dfsg1-3 precisely depends on the new version of mathpiper).

[Launchpad Janitor (janitor)]

This bug was fixed in the package geogebra - 4.0.19.0+dfsg1-4

---------------
geogebra (4.0.19.0+dfsg1-4) unstable; urgency=low

  * Add stricter dependecies also to the binary package, not only
    to the source.
