Package: cantor
Version: 4:4.8.4-2
Severity: normal
I did a fresh install of cantor and cantor-backend-[maxima,kalgebra] today.
In trying to display a LaTeX rendered formula in Cantor I did the following
steps:
1. Type 'expand((x+y)^2);' and evaluate it. This will return the latex code
that need to be rendered: \begin{eqnarray*}y^2+2\,x\,y+x^2\end{eqnarray*}
2. Insert a new text entry, write $$ (latex from above) $$ and evaluate it.
This makes this text (in the text entry) disappear, just the empty box
frame is left.
3. Trying to click into it leads to a crash (and Dr. Konqi).
The packages recommended by cantor, texlive-latex-base and texlive-binaries,
are installed. (In fact, Lyx is installed with a pretty complete set of
Texlive packages.)
After installing the debug packages (for cantor and qt) I got a couple (not
so good) backtraces:
Application: Cantor (cantor), signal: Segmentation fault
