Crash on startup with mime rule expressions in paranthesis using logical AND

[michaelrsweet]

Many mime rules that:

begin with an expression in parenthesis, have the first expression followed by an AND operator

will cause a crash in cupsd on startup. The error is "cupsd: Child exited on signal 11!" I have not been able to determine the exact syntax that trips this error. In some cases, meeting the above conditions for a crash will not cause a crash.

The following will crash when starting cupsd:

---

application/vnd.hp-HPGL (hpgl) + string(0,<1B>E<1B>%0B)

---

application/vnd.hp-HPGL (hpgl) + \ string(0,<1B>E<1B>%0B)

---

However, these will not crash

application/vnd.hp-HPGL string(0,<1B>E<1B>%0B) + (hpgl)

application/vnd.hp-HPGL (hpgl) , string(0,<1B>E<1B>%0B)

application/vnd.hp-HPGL hpgl + string(0,<1B>E<1B>%0B)
