Don't increase iterator after it's already at the end

Don't increase it after it's already at the end. We are increasing the iterator inside of the loop, and as part of the for so it'll be past the end and the it != l.constEnd() will be true and we will crash.

Changed the code so that it only increases the iterator if we know it's not at the end already.

Did some stand-alone code that runs over

const char * processResult = "p1445\ncchrome\nf5\nf6\nf12\nf13\nf16\nf17\nf21\nf22\nf26\nf27\nf32\nf33\np1453\ncchrome\nf6\nf7\np1528\ncdbus-launch\nf8\np1530\ncenlightenment\nf5\nf6\nf10\nf11\nf34\nf37\nf38\np1533\ncefreetd\nf6\nf7\np1540\ncgvfsd\nf6\nf7\np1565\ncterminology\nf5\nf6\nf10\nf11\np1566\ncfirefox\nf10\nf11\nf12\nf13\nf14\nf15\nf22\nf23\nf161\nf162\np1619\ncenlightenment_f\nf5\nf6\np1631\nctempget\nf1\nf5\nf6\nf37\nf38\np1679\ncat-spi-bus-laun\nf5\nf6\np1736\ncplugin-containe\nf6\nf7\nf11\nf12\np1822\ncthunderbird\nf10\nf11\nf12\nf13\nf14\nf15\nf21\nf22\nf44\nf176\np2261\nckdeinit4\nf0\nf3\nf5\np2263\ncklauncher\nf0\nf3\nf4\nf5\nf6\nf10\nf11\np2265\nckded4\nf0\nf4\nf6\np2267\ncgam_server\nf6\nf7\np2346\nckuiserver\nf0\nf4\nf6\np2381\ncknotify4\nf0\nf4\nf6\np2633\nck3b\nf5\nf6\nf14\nf21\nf22\nf25\nf26\nf28\nf33\nf34\np2791\nclsof\nf0\nf1\nf2\nf4\nf5\np2792\nclsof\nf3\nf6\n";

And it crashed, now doesn't crash anymore
