The problem is this comparison: if len(tag_text)>0 this line causes the same error if tag_text!=[] So I assume the problem is caused somwhere in vim C source code?
You need to build Vim with debug information and run Vim from gdb and execute the above code. When Vim crashes, you should be in the gdb prompt and you can get additional information about this crash. - Yegappan
