In a register, if one enter any custom action which it's not listed it will crash GnuCash
Sorry, that doesn't make sense. Please write a step-by-step procedure to reproduce the crash.
Unable to reproduce the obvious (entering something into the split action field that's not in the drop-down list), no further information from reporter. Ruben Cheng, if at some point you're motivated to provide detailed information about how you induced the crash you may reopen the bug.
Hi.. I did these steps to reproduce the failure... With a new file 1) Create a new file, with "Common Accounts" categories template. Save the file 2) Open Cash in Wallet 3) Enter a transaction, filling the fields Date, Description (Test), Transfer (with any categoriess. I tried Expense:Auto), Spend (20). Num, action and Notes are empty. 4) You will have a new empty transaction to enter. Above is the created in step (3) 4) Select last new transaction 5) Select Action field. It will list: Buy, Decrease, Increase, Sell. 6) Instead select any, enter any word, for example "crash" 7) it will close GnuCash without error
Perfect, I was able to easily reproduce and fix. It will be in tonight's nightly and GnuCash 4.6.
