Commit 8becb2da8fdbec5252118e2172fcb3f0fca6f041

Fix segfault in src/filehandling_functions.c. We were strdup()ing the result of getenv() without checking whether it was NULL. Further, we were using the result as an array without checking whether *it* was NULL. Both wrapped in a null pointer check.
