I am experiencing the same crash whenever I try to double click on the first word in a text file to copy and paste. If I drag to manually select the word it works fine, but as soon as I double click to select the whole word, it crashes. It happens on both my desktop and laptop, and only seems to be the first word in a text file. Hope you are able to fix it - Textastic is a really great app!
