Segfault related to ledger.session.close_journal_files() and running a function after calling this function. However, the segfault doesn't happen with any input file. The input below will trigger the segfault.

Python file:

import ledger

journal = ledger.read_journal("d")
ledger.session.close_journal_files()
account = journal.find_account_re("foo")

Input file "d":

2012-01-04 * foo foo foo foo foo foo foo foo foo foo foo foo foo foo
Assets:A 273.57 GBP
Assets:B

2012-01-04 * bar bar bar bar bar bar bar bar bar bar bar bar bar bar
; Fund: bar
Assets:A 86.39 GBP
Assets:B

Program received signal SIGSEGV, Segmentation fault.
