GnuCash OFX account setup crashes with assertion failure

[cdurst]

Binary package hint: libaqbanking20-plugins-qt

This applies to both Ubuntu 8.04 and 8.10, (ever since Ubuntu shipped aqconnect).

It worked in GnuCash 2.2.1 (aqbanking-3.99.6beta built from source).
It fails on gnucash-2.2.6 (libaqbanking20-3.5.1-1).

The problem:
It crashes while setting up an online banking account, following the instructions in "Setting up OFXDirectConnect in GnuCash 2" (http://wiki.gnucash.org/wiki/Setting_up_OFXDirectConnect_in_GnuCash_2).

I start the aqBanking wizard (with Tools-> Online Baking Setup),
I then "Start AqBanking Wizard",
I select the "Users" tab,
I bring up the dialog to create a "New" user,
I fill in all the data. Note that as far as I can tell, it crashes before it even tries to log in, so you probably don't need a valid account to test this.

For example, in the "General" tab:
   User Settings
      User Name: anything
      User Id: (my DiscoverCard login id)
      Customer Id: (same as the User ID)
   Bank Settings
      Country: United States of America
      Bank Id: 7101
In the OFX tab:
   Bank Settings
      FID: 7101
      ORG: Discover Financial Services
      Broker Id: (leave blank)
   Connection Settings
      Server URL: https://ofx.discovercard.com/
   Server Options
      Supports Account List Download (SELECT)
      Supports Statement Download (SELECT)
      Force SSLv3 (SELECT)
      (Leave all others blank)
   Expert Settings (Leave alone)

Then press the "Get Accounts" button and it will crash with messages like this:
   aqbanking(14182):qbanking.cpp: 420: No Qt translation found for your language en
   gwen(14182):dbrw.c: 963: open(/home/user/.aqbanking/shared/qbanking/settings.conf, O_RDONLY): No such file or directory
   qt3_wizard(14182):qbcfgtabpageusers.cpp: 149: Selected backend: aqofxconnect
   qt3-wizard: buffer.c:987: GWEN_Buffer_AppendString: Assertion `buffer' failed.

For many months I've tried everything I could think of. I Googled every combination I could think of, I tried out various updates, I downloaded the source, compiled it myself, and even tried debugging it with GDB. The assertion failure seemed to happen when it tried to access a "user" field while attempting to construct the message to send to the banking site (from what I can remember).

Today I found a workaround.

Do not push the "Get Accounts" button while setting up a "New User". Instead, hit the "OK" button to finish user creation, then select that new User from the "Configuration" dialog, edit the user using the "Edit" button, switch back to the "OFX" tab you were on a moment ago, and now hit the "Get Accounts" button.

It looks like the "Get Accounts" button is ignoring the current entries in the "User Configuration" dialog, and only using the entries that have previously been saved out to the overall "Configuration" dialog.

Can you please re-try to reproduce this bug with a more recent version of libaqbanking20?

[balak (balak)]

First of all, thank you cdurst for this bug report and the work-around. I was dealing with this problem for several days and finally stumbled upon the solution through a google search.

I see the same issue in ubuntu intrepid (amd64). Here are the appropriate versions of gnucash and libaqbanking:
 dpkg -l | grep gnucash
ii gnucash 2.2.6-2ubuntu3 A personal finance tracking program
ii gnucash-common 2.2.6-2ubuntu3 A personal finance tracking program
ii gnucash-docs 2.2.0-3 Documentation for gnucash, a personal financ

$ dpkg -l | grep libaqbank
ii libaqbanking-data 3.5.1-1 configuration files for libaqbanking
ii libaqbanking-plugins-libgwenhywfar47 3.5.1-1 library for online banking applications plug
ii libaqbanking20 3.5.1-1 library for online banking applications
ii libaqbanking20-plugins 3.5.1-1 plugins needed by libaqbanking20
ii libaqbanking20-plugins-qt 3.5.1-1 plugins needed by libaqbanking20

These are latest version in the repositories. If you would like me to try out the newer versions, can you point me how/where to get them.

Thanks!

[Micha Lenk (micha)]

balak, apparently you found a solution. How did you solve the problem?

This bug is very likely related to http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=505509

Can you please confirm that a newer libaqbanking version fixes the problem?

Regards
  Micha

[balak (balak)]

Micha, I read through the debian bug. Yes, this is the same issue as mentioned in the other bug report.

The workaround was described by cdurst. Once you enter all the information to the wizard, don't use the "Get Accounts" buttton but close it by pressing 'OK'. The accounts can be retreived later on by "edit"ing the same user and using the "Get Accounts"

Can you let me know how to get the new version of libaqbanking (for ubuntu intrepid). Thanks!

[Micha Lenk (micha)]

I've just triaged this bug with libaqbanking 4.1.0 on Debian Lenny. Whereas the particular bug described in Debian bug #505509 seems to be fixed, there is apparently another one, leading to a segfault too:

3:2009/08/05 12-42-29:aqbanking(7474):qbanking.cpp: 420: No Qt translation found for your language C
3:2009/08/05 12-42-36:qt3_wizard(7474):qbcfgtabpageusers.cpp: 165: Selected backend: aqofxconnect
qt3-wizard: cfgdir.c:284: GWEN_ConfigMgrDir_AddGroupFileName: Assertion `subGroupName' failed.
Aborted

I will investigate this and report back later.

[Micha Lenk (micha)]

I've triaged it again with AqBanking current trunk from upstream SVN (rev. 1729) and still got a segfault. The console output is on the previous message. The backtrace is:
