Just wanted to say, I had the same problem on my phone,

opera mobile 26 on xperia Z1C running kitkat 4.4.4

basically crashing after viewing a wikipedia page...
read through this and the other thread, so updated to version 37 and everything's running ok once again 🙂

As a note, I WAS able to get to my install directory by using the "backup & restore" app on the phone, and using this https://nelenkov.blogspot.co.uk/2012/06/unpacking-android-backups.html
which in theory would also then allow me to 'repack' and restore

Thanks all
