Unable to start WhatPulse

I installed WhatPulse yesterday and it was working fine this morning but I noticed it isn’t running anymore. When I run it on my terminal (Ubuntu 12.04) I get the following error:

Application crashed with signal 11! 0 [./whatpulse(_ZN11Application21geoIPDownloadFinishedEb7QString+0x6d) [0x488d9d]] 1 [./whatpulse() [0x59b903]] 2 [/usr/lib/x86_64-linux-gnu/libQtCore.so.4(_ZN11QMetaObject8activateEP7QObjectPKS_iPPv+0x2b1) [0x7f0d92d46281]] 3 [./whatpulse(_ZN13Communication21finishGeoIPDBDownloadEb7QString+0x35) [0x5a2e45]] 4 [./whatpulse(_ZN13Communication21GeoIPDownloadFinishedEv+0x107) [0x4d12c7]] 5 [./whatpulse() [0x5a2e81]] 6 [/usr/lib/x86_64-linux-gnu/libQtCore.so.4(_ZN11QMetaObject8activateEP7QObjectPKS_iPPv+0x2b1) [0x7f0d92d46281]] 7 [/usr/lib/x86_64-linux-gnu/libQtNetwork.so.4(+0x83fe6) [0x7f0d9310dfe6]] Aborted

Any idea what the problem might be?
