This is not a bug. It is a well known limitation when running the kernel on a headless server on Linux. Some operations require the Front End. Importing TeX is such an operation. The Front End requires an X server, regardless of what it's being used for. Simple solution: use Xvfb as the X server. Ref: ...

After managing to reproduce the problem (using Mathematica 8.0.0.0) and looking into an strace I come to the following result: After issuing the ToExpression["x=4-2", TeXForm], the kernel start a front end: 15166 execve("[...]/SystemFiles/FrontEnd/Binaries/Linux-x86-64/Mathematica", ["[...]/SystemFiles/F"..., "-topDirectory", "/misc/psi/math-8.0", ...

Here are three progressively more intrusive steps to troubleshoot Mathematica. Hold down Shift-Control (Shift-Command on Mac) while starting Mathematica, as described here. If this didn't fix the problem, move to the next step. Evaluate SystemOpen[$UserBaseDirectory]. This will reveal the directory where Mathematica keeps all its settings, packages, ...
